10 + 80 = 90 subtract 90 to other numbers to get more equations
(+3x+4y=2)
(+4x-4y=12)
-----------------
7x = 14
-----------------
7
X=2
3(2)+4y=2
6+4y=2
4y=-4
Y=-1.
Or you can plug x into the other equation.
4(2)-4y=12
8-4y=12
-4y=4
Y=-1.
I think it’s 1/6 or 0.16, those two are basically the same thing
