What are two step equations
miskamm [114]
2 step equations are equations that require 2 steps to solve it.

For example, 2x + 5 = 3x + 6

To solve for x, we must isolate it.

First subtract 2x on both sides, which is ONE step.

2x + 5 = 3x + 6
-2x         -2x

5 = x + 6

The we must subtract 6 from both sides of the equation, which makes is the second step.

5 = x + 6
-6       -6

-1 = x 

-1 would be the answer and we only used 2 steps to solve it.
