5m-2n=-4
3m+4n=34
double the first equation
10m-4n=-8
3m+4n=34
13m=26
m=2
5(2)-2n=-4
10-2n=-4
-2n=-14
n=7

5m-2n=-4
3m+4n=34
------
Modify for elimination::
10m - 4n = -8
3m + 4n = 34
-----
Add and solve for "m":
13m = 22
m = 22/13
------
Solve for "n":
3m + 4n = 34
3(22/13) + 4n = 34
(66/13) + 4n = 34
-------
66 + 52n = 13*34
52n = 246
n = 123/26 = 4.73
