Question

(y-4) (y-6)= 15
solve for y​

Answer 1

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

solve brackets

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

Now,

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

18y=12

y=12/18

y=2/3

Answer 2

Answer:

No solution

Step-by-step explanation:

${y}^{2} - 6y - 4y + 24 = 15 \\ {y}^{2} - 10y + 24 = 15 \\ {y}^{2} - 10y + 9 = 0 \\ {y}^{2} - 9y + y + 9 = 0 \\ y(y - 9) + 1(y + 9) = 0$
