Question

2/3 (y + 57) = 178

(Answer with explanation)

Answer 1

Explanation:

`(2)/(3)`(y + 57) = 178

distribute
`(2)/(3)` into the parentheses

`(2)/(3)`y + 38 = 178

-38 -38

`(2)/(3)`y = 140

multiply both sides by the reciprocal of
`(2)/(3)` which is
`(3)/(2)`

(
`(3)/(2)` )
`(2)/(3)`y = 140(
`(3)/(2)` )

`(2)/(3)` is cancelled out with only y remaining on the left side

y = 210
