+660 Find an ordered pair (x,y) that solves the system:
Sorry that the image is so big, make sure you scroll to the right.
2x - 3y = -3.2 - 0.2x + 0.1y
x = 0.6x - y + 8.8
2.2x - 3.2 = 3.1y
0.4x + y = 8.8
y = 8.8 - 0.4*x
2.2x - 3.2 = 3.1(8.8 - 0.4*x)
2.3x - 3.2 = 27.28 - 1.24x
3.54x = 30.48
x = 508/59
Pluggin into y = 8.8 - 0.4*x, we get y = 8.8 - 0.4*508/49 = -3782/1475
So the solution is (508/49, -3782/1475)
