(y+2)/(y) = 1/(y-5)

Directions:

Solve the rational expression.

Remember that if:

a/b = c/d

then:

a * d = b * c

I believe in school they call this the fraction crossover rule or fraction cross rule or something like that.

i would work it like a proportion and cross multiply and then divide.

(y+2)/(y) = 1/(y-5)

(y-5)(y+2) = y

y^2-3y-10 = y

y^2-4y-10 = 0

Since there are no factors of 10 whose difference is 4, use the quadratic formula to solve.
