Answer:
The value of y is 6.
Step-by-step explanation:
The given equation is

It can be rewritten as


Multiply both sides by (y+4)(y-4).







Divide both sides by -2.

Therefore, the value of y is 6.
EQUATION: 5x = 2x - 9
Add 9 to both sides
NEW EQUATION: 5x + 9 = 2x
Subtact 5x from both sides:
NEW EQUATION: 9 = -3x
Divide -x on bith sides
NEW EQUATION: -3 = x, or x=-3
