Example Question #49 : How To Solve One Step Equations With Integers In Pre Algebra

Solve for  when 

Possible Answers:

Correct answer:

Explanation:

To solve for  we must get all of the numbers on the other side of the equation as .

To do this in a problem where  is being multiplied by a number, we must divide both sides of the equation by the number.

In this case the number is  so we divide each side of the equation by  to make it look like this 

The 's cancel to leave  by itself 

Then we perform the necessary division to get the answer of .

Example Question #50 : How To Solve One Step Equations With Integers In Pre Algebra

Solve for  when 

Possible Answers:

Correct answer:

Explanation:

To solve for  we must get all of the numbers on the other side of the equation as .

To do this in a problem where a number is being added to , we must subtract the number from both sides of the equation.

In this case the number is  so we subtract  from each side of the equation to make it look like this 

The 's on the left side cancel to get .

Then we perform the necessary subtraction to get the answer of .
