Homework Help: Algebra

Solve the system

9x-5y=119
18x-10y=238

Double both sides of the first equation and you have
18x-10y =238
which is the same as the second equation. Since the two equations are not independent, there are no unique solutions. Thee are an infinite number of pairs of x and y that will work.
