18 = 3x + y y = 18 - 3x Now plug it in instead of y in the other equation and solve for x.
OpenStudy (anonymous):
Ok,I got x=52/11.
OpenStudy (anonymous):
Check you answer, x = 4.
OpenStudy (anonymous):
Can you please explain how to get that answer?
OpenStudy (anonymous):
4x = 3y - 2 I plug in y = 18 - 3x 4x = 3(18 - 3x) -2 4x = 54 - 9x -2 13x = 52 x = 4
