M = 135/19 and n = -5/19
You have to give them like terms so that when you eliminate they cancel out and you can solve. The easiest way to do so is by multiplying the top equation by -4 and the bottom by 3.
2x+10=0
subtract 10 from both sides
2x=(-10)
divide 2 from both sides
x=-5
69, 70, 71, and 72
