Exercise 46 Page 560

Isolate the variable on one side of the equation.

x=180

Practice makes perfect

In order to solve an equation, we need to isolate the variable on one side of the equation. To do this, we first will multiply both sides of the equation by 2 and then we will add 30 to both sides.

75=1/2(x-30)

LHS * 2=RHS* 2

150=x-30

LHS+30=RHS+30

180=x

Rearrange equation

x=180

Therefore, the value of x is 180.
