(15 +y) / (y) + (36+y) / (y) =155
multiply each term by y
15+y + 36+y = 155y

continue
51 +y = 155y
51 = 155y -y
51=154y
0.33=y
now how do i get the restriction
hello, why no response
as with all of these rational functions, the restrictions are all values where the denominator is zero.
Because division by zero is undefined.
