Question

15(y-4)-2(y-9)+5(y+6)=0

Answer 1

15y-60-2y+18+5y+30=0
15y-2y+5y=0+60-18-30
13y+5y=60-48
18y=12
y= 12÷18
y=0.666

Answer 2

Answer :

15 ( y - 4 ) - 2 ( y - 9 ) + 5 ( y + 6 ) = 0
15 y - 60 - 2y + 18 + 5y + 30 = 0
18y - 12 = 0
18y = 12
y = 12 / 18
y = 2 / 3

Hope you got your answer.

Best of luck for your future.
