Answer:
2y-4-6y-12=4
-4y=20
y= -5
Step-by-step explanation:
because (y+2)(y-2)=y^2-4
so we have the step to let the every part have the same denominator y^2-4
2(y-2)/(y+2)(y-2) -6(y+2)/(y-2)(y+2)=4/(y-2)(y+2)
the denominators are the same so the equality .we just need the part over be the same 2y-4-6y-12=4
y= -5
The answer is $14 because 65% of $40 is 26 and 40-26=14
