3m-4n=1
3m-2n=-1
I wouldn't graph because I'm lazy

I wouldn't subsitute because I'm too lazy to put it into a form m=something or n=something

i would eliminate because the m's are both 3, just multiply the top equaiton by -1 and add them equations to get 2n=-2, so n=-1,then m=-1 so then (-1,-1) is solution

eliminate
