Question

15(y - 4)-2 (y– 9) +5 (y + 6) = 0


please give answer short​

Answer 1

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

15y-60-2(y-9) +5(y+6) =0

15y-60-2y+18+5y+30=0

15y-2y+5y-60+18+30=0

18y-12=0

18y=12

y=12/18

y=2/3

Mark me as a brainliest!

Answer 2

Answer:

»Question -

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

» Answer -

15y -60 -2y +18+5y+30 = 0

(15y-2y+5y) + (-60+18+30) = 0

(20y -2y) + (-12) = 0

18y - 12 = 0

18y = 12

$y = \frac{12}{18} \\ \\ \\</p><p>{\pink{\boxed{y = \frac{2}{3}}}}$
