Example Questions

Example Question #351 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle x+512=893\)

Possible Answers:

\(\displaystyle 1405\)

\(\displaystyle 1205\)

\(\displaystyle 673\)

\(\displaystyle 391\)

\(\displaystyle 381\)

Correct answer:

\(\displaystyle 381\)

Explanation:

\(\displaystyle x+512=893\) Subtract \(\displaystyle 512\) on both sides.

\(\displaystyle x=381\)

Example Question #352 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle x+609=423\)

Possible Answers:

\(\displaystyle 186\)

\(\displaystyle 1032\)

\(\displaystyle -176\)

\(\displaystyle -1032\)

\(\displaystyle -186\)

Correct answer:

\(\displaystyle -186\)

Explanation:

\(\displaystyle x+609=423\) Subtract \(\displaystyle 609\) on both sides. Since \(\displaystyle 609\) is greater than \(\displaystyle 423\) and is negative, our answer is negative. We treat as a subtraction problem.

\(\displaystyle x=-186\)

Example Question #353 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle x+234=-777\)

Possible Answers:

\(\displaystyle 692\)

\(\displaystyle -543\)

\(\displaystyle 1011\)

\(\displaystyle -1011\)

\(\displaystyle 543\)

Correct answer:

\(\displaystyle -1011\)

Explanation:

\(\displaystyle x+234=-777\) Subtract \(\displaystyle 234\) on both sides. When adding two negative numbers, we treat as an addition problem and add the minus sign in the end.

\(\displaystyle x=-1011\)

Example Question #354 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle x-380=275\)

Possible Answers:

\(\displaystyle 655\)

\(\displaystyle 755\)

\(\displaystyle 555\)

\(\displaystyle 105\)

\(\displaystyle -105\)

Correct answer:

\(\displaystyle 655\)

Explanation:

\(\displaystyle x-380=275\) Add \(\displaystyle 380\) on both sides.

\(\displaystyle x=655\)

Example Question #351 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle x-450=-274\)

Possible Answers:

\(\displaystyle 176\)

\(\displaystyle -724\)

\(\displaystyle -176\)

\(\displaystyle 724\)

\(\displaystyle 318\)

Correct answer:

\(\displaystyle 176\)

Explanation:

\(\displaystyle x-450=-274\) Add \(\displaystyle 450\) on both sides. Since \(\displaystyle 450\) is greater than \(\displaystyle 274\) and is positive, our answer is positive. We treat as a subtraction problem.

\(\displaystyle x=176\)

Example Question #356 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle x-461=-579\)

Possible Answers:

\(\displaystyle -1040\)

\(\displaystyle -108\)

\(\displaystyle -118\)

\(\displaystyle 118\)

\(\displaystyle 1040\)

Correct answer:

\(\displaystyle -118\)

Explanation:

\(\displaystyle x-461=-579\) Add \(\displaystyle 461\) to both sides. Since \(\displaystyle 579\) is greater than \(\displaystyle 461\) and is negative, our answer is negative. We treat as a subtraction problem.

\(\displaystyle x=-118\)

Example Question #357 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle 13x=585\)

Possible Answers:

\(\displaystyle 75\)

\(\displaystyle 45\)

\(\displaystyle 35\)

\(\displaystyle 65\)

\(\displaystyle 55\)

Correct answer:

\(\displaystyle 45\)

Explanation:

\(\displaystyle 13x=585\) Divide \(\displaystyle 13\) on both sides.

\(\displaystyle x=45\)

Example Question #358 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle -48x=1200\)

Possible Answers:

\(\displaystyle 25\)

\(\displaystyle 35\)

\(\displaystyle -35\)

\(\displaystyle -25\)

\(\displaystyle -60\)

Correct answer:

\(\displaystyle -25\)

Explanation:

\(\displaystyle -48x=1200\) Divide \(\displaystyle -48\) on both sides. When we divide with a positive number, our answer is negative.

\(\displaystyle x=-25\)

Example Question #359 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle -23x=-322\)

Possible Answers:

\(\displaystyle 16\)

\(\displaystyle 19\)

\(\displaystyle 18\)

\(\displaystyle 14\)

\(\displaystyle 24\)

Correct answer:

\(\displaystyle 14\)

Explanation:

\(\displaystyle -23x=-322\) Divide \(\displaystyle -23\) on both sides. When dividing with another negative number, our answer is positive.

\(\displaystyle x=14\)

Example Question #360 : How To Solve One Step Equations

Solve for \(\displaystyle x\).

\(\displaystyle \frac{x}{12}=67\)

Possible Answers:

\(\displaystyle 824\)

\(\displaystyle 804\)

\(\displaystyle 814\)

\(\displaystyle 784\)

\(\displaystyle 794\)

Correct answer:

\(\displaystyle 804\)

Explanation:

\(\displaystyle \frac{x}{12}=67\) Multiply \(\displaystyle 12\) on both sides.

\(\displaystyle x=804\)
