HELP!!! Solve using elimination.
2m+3n=12
-5m+n=-13

I know how to do it but I'm just getting the weirdest answer...
I got m = -27/17 and n= 86/17.
Help would be GREATLY appreciated!

2m + 3n = 12
-5m + n = -13
----------------
Multiplying each side by 3 on the second equation...
2m + 3n = 12
-15m + 3n = -39
----------------
Subtracting both equations...
17m = 51

@chandhooguy You'd have to multiply by -3 because 3n has to cancel out by it's opposite :)

ddw, I subtracted each side, so I canceled them out when I did that.

Ok, so multiply the 2nd equation by -1 and see what you get.
