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)
