### Example Question #9 : Two Step Equations With Decimals

Solve the equation for .

Explanation:

The correct answer to this question is .

To start, you need to move 's one one side of the equation and numbers to the other side of the equation:

First, you subtract  from both sides of the equation. Then, you will have put all of the 's on the same side of the equation:

Next, you add  to the left side of the equation to put all of the numbers on the same side of the equation:

Once you do this, you can add the numbers on the left side of the equation together and find that .

Solve for x:
