... = —————— – —————— – —————— = 0
(y - 6)(y - 4) (y - 4)(y + 4) (y - 6)(y + 4)
y ≠ 6 , y ≠ 4 , y ≠ -4 LCD = (y - 6)(y - 4)(y + 4)
3(y + 4) y – 6 6(y - 4)
———————— – ———————— – ——————— = 0
(y-6)(y-4)(y+4) (y-6)(y-4)(y+4) (y-6)(y-4)(y+4)
3y + 12 - y + 6 - 6y + 24 -4y + 42
————————————— = 0 ---> ———————— = 0
(y - 6)(y - 4)(y + 4) (y-6)(y-4)(y+4)
-4y + 42 = 0 ---> -4y = -42 ---> y = 10.5
