Write two fractions with different denominators whose LCD (lowest common denominator) is 36.

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Find the solution of this system of equation -7x+y=-20 9x-3y=36
