Question 705832: 2m+3n=4
-m+2n=5

You can put this solution on YOUR website!
Hint: Double every value in the second equation to get -2m+4n=10

Then add this new equation to the first equation to get

2m+3n=4
-2m+4n=10
---------
0m+7n=14


So 7n = 14. Solve for n. Then use the solution for n to find the solution for m.
