solve each system of equations
1.4x-0.5y=1.3
0.4x+1.1y=4.1

• algebra -

I find it easier to deal with integers, so my first step would be

14x - 5y = 13
4x + 11y = 41

now, to eliminate the y's, do some multiplying to get

154x - 55y = 143
20x + 55y = 205

add them together to get

174x = 348
x = 2
so, y = 3
