You can put this solution on YOUR website!
-2m = 6m - 9 you have to find m:
0=2m+6m-9
8m-9=0
8m=9
m=9/8
Solution: m=9/8
6s - 11 = -2s + 5 you have to find s
6s+2s=11+5
8s=16
s=2

-2m+=+6m+-+9 ---------------> eqn 1
6s+-+11+=+-2s+%2B+5 -------------> eqn 2
In eqn 1:
9=6m%2B2m, combine similar terms and change sign "+" or "-" if needed
9=8m --> 9%2F8=cross%288%29m%2Fcross%288%29
m=9%2F8, ANSWER
In eqn 2:
6s%2B2s=5%2B11, combine terms like in eqn 1
8s=16 --> cross%288%29s%2Fcross%288%29=cross%2816%292%2Fcross%288%29
s=2, ANSWER
Thank you,
