Question

Solve the system with the substitution method...i am not able to get this stuff right... n=-6m-4

14m+2n=-8

Answer 1

Since the first equation gives you what n equals, plug it into the second equation:
14m+2(-6m-4)=-8

Then distribute the two:
14m-12m-8=-8

Move the eight and combine like terms.:
2m=0

Divide and you get m=0. Now to find n simply plug in m to either equation:
14(0)+2n=-8 or n=-6(0)-4

Either way you get n=-4.
