## A Tutorial on Solving Equations Part 3

This is the third part of the series of tutorials on solving equations. In this part, we will solve more complicated equations especially those that contain fractions. The first part and the second part of this series discuss 10 sample equations. We start with the 11th example.

**Example 11**: -5*x* – 3 = -4*x* + 12

This example deals with the question of what if is negative? Let us solve the equation. We want on the left and all the numbers on the right. So, we add 4x to both sides.

-5*x* – 3 + 4*x* = -4*x* + 4*x* + 12

–*x *– 3 = 12

Next, we add 3 to both sides to eliminate -3 from the left hand side of the equation. Continue Reading
