Question

2m+5n=12
-6n+m=-11

Answer 1

Multiply second equation by -2 and tell me what u get.

Answer 2

uh 12n+2m=22?
i don't understand where the -2 came from though

Answer 3

sure 2m or -2m ??
i wanted to make the co-efficient of m as -2(the co-efficient of m in first equation is +2), so that when i add 2 equations, m gets eliminated (-2m+2m=0)
got this ?

Answer 4

ohhh okay. what do i do now?

Answer 5

2nd equation : 12n-2m=22
1st equation : 5n +2m =12
ADD them.
