Solving Equations with Variables (Jump to: Lecture | Video )

Imagine you have an equation that has variables on both sides:

4x + 2 = 2x + 6

This equation can be solved using the properties of equality we already know.

Our goal is to get a single x on its own. First, we subtract 2 from each side:

4x = 2x + 4

Next, we subtract 2x from each side:

2x = 4

Next, we dicide each side by 2

x = 2
