Y cannot equal what?

Question

9y+7 over y-3 + 5y+6 over y-3

Answer 1

Your expression consists of two fractions being added:

(9y + 7)/(y - 3) + (5y + 6)/(y - 3)

(y - 3) is denominator and it cannot equal “0” (“0” in denominator will make a fraction undefined)

y - 3 = 0

y = 3

Answer: “y” cannot equal “3”.
