You can use substitution or addition to solve the system. By substitution you need to solve one of the equations for x or y, then plug in that into the other equation replacing x or y.
OpenStudy (anonymous):
For example, your second equation solved for y would be y=(18+10x)/7
OpenStudy (anonymous):
Then replace that into the first equation, giving you 5x+(18+10x)/7 = 9
OpenStudy (anonymous):
Solve for x first, then you can solve for y once you have the value of X
OpenStudy (anonymous):
so y=9 is the answer
