Question

If 3x/4 - 13 = -9 then what is the value of x^2

Answer 1

x² =
`(256)/(9)`

Explanation:

`(3x)/(4)` - 13 = - 9 ( add 13 to both sides )

`(3x)/(4)` = 4 ( multiply both sides by 4 to clear the fraction )

3x = 16 ( divide both sides by 3 )

x =
`(16)/(3)`

Then

x² = (
`(16)/(3)` )² =
`(16^2)/(3^2)` =
`(256)/(9)`
