Question

Solve the equation using the distributive property and properties of equality.

1 / 2 ( x + 6) = 18
What is the value of x?
6
14.1
30

Answer 1

x=30

Explanation:

1 / 2 ( x + 6) = 18

Distribute

1/2x +3 = 18

Subtract 3 from each side

1/2x +3-3 = 18-3

1/2x = 15

Multiply each side by 2

1/2x*2 =15*2

x = 30
