Question

1/2(-9 + y)=2.5 solve for why. Please show me your steps

Answer 1

`(1)/(2) ( - 9 + y) = 2.5 \\ - 4.5 + 0.5y = 2.5 \\ minus \: - 45 \: both \: sides \: of \: the \: equation \\ (0.5y)/(0.5) = - ( 7)/(0.5) \\ y = 14`

Answer 2

Y = 14

Explanation:

1/2(-9 + y) = 2.5

1/2 * -9 = -4.5

1/2 * y = 0.5y

-4.5 + 0.5y = 2.5

+4.5 +4.5

0.5y = 7

/0.5 /0.5

y = 14
