1.5

Practice makes perfect

To solve an equation, we should 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.

5x=2-(x-7)

Distribute -1

5x=2-x+7

LHS+x=RHS+x

6x=9

.LHS /6.=.RHS /6.

x=9/6

a/b=.a /3./.b /3.

x=3/2

Write as a decimal

x=1.5

The solution to the equation is x=1.5.
