Question

2/3•x-9=12 solve for x?

Answer 1

`x=(63)/(2)`

Explanation:

`(2)/(3) * x-9=12`

Add 9 to both sides:

`(2)/(3)x-9+9=12+9\\(2)/(3)x=21`

Multiply both sides by 3/2:

`((3)/(2) )*((2)/(3)x)=((3)/(2) )*(21)\\x=(63)/(2)`

x = 63/2 is your answer.

Answer 2

31.5

Explanation:

Ok.

2/3x - 9 = 12

2/3x = 21

x = 21*(3/2)

x = 63/2 = 31.5
