You can put this solution on YOUR website!
Solve for m:
9-%282m%2F7%29+=+19 Subtract 9 from both sides. You were ok on this step!
-2m%2F7+=+10 Now multiply both sides by 7.
%28-2m%2Fcross%287%29%29%2Across%28%287%29%29+=+7%2A10 Simplify.
-2m+=+70 Finally, divide both sides by -2.
highlight%28m+=+-35%29
