Example Question #281 : How To Solve Two Step Equations

Solve the equation: 

Possible Answers:

Correct answer:

Explanation:

Subtract two fifth from both sides of the equation.

Simplify both sides. In order to subtract the right side, we will need to have like-denominators. Find the least common denominator and re-convert the fractions.

Subtract the numerators on the right side.

Multiply by two on both sides to eliminate the fraction in front of the x-variable.

The answer is:

Example Question #824 : Linear Equations

Solve

Possible Answers:

Correct answer:

Explanation:

Solving for a linear two-step problem is simple. It's just a matter of solving for x. Just think "how do I get x by itself?" In this type of problem, it is crucial to remember that what you do to one side you must do to the other. 

In the case for ,

the first step for getting x by itself is to subtract  from both sides. 

Comparing the original problem to what it looks like after subtracting  from both sides, we can deduce that we're closer to getting x by itself. The only thing left to do is dividing both sides by . This will give the final answer for x.

Example Question #291 : How To Solve Two Step Equations

Solve the following equation for x:

Possible Answers:

Correct answer:

Explanation:

We must begin by isolating all variables. To do this, we use inverse operations. In other words, we must add  to both sides of the equation. This leaves us with .

Finally, we again use inverse operations: in this case, division. When we divide both sides by , we are left with .
