Exercise 40 Page 412

Gather all of the variable terms on one side of the equation and all of the constant terms on the other side.

x=2

Practice makes perfect

To solve an equation, we should first gather all of the variable terms on one side of the equation and all of the constant terms on the other side, using the Properties of Equality. In this case, we will start by adding 2x to both sides of the equation.

11-2x=5x-3

AddEqn

LHS+2x=RHS+2x

11-2x+2x=5x-3+2x
