Question

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x - 2)?

Answer 1

x=4

Explanation:

multiply everything out

1.5x+6-3=4.5x-9

simplify

1.5x+3=4.5x-9

get all the varibles on one side

12=3x

divide by 3

x=4

Answer 2

x=4

Explanation:

1.5(x + 4) – 3 = 4.5(x - 2)?

1.5x + 6 - 3 = 4.5x - 9

1.5x + 3 = 4.5x - 9

1.5x + 3 + 9 = 4.5x

1.5x + 12 = 4.5x

12 = 4.5x - 1.5x

12 = 3x

12/3 = x

4 = x

x = 4
