    Well you need to either get "x" or "y" alike so they can cancel

    Ok so do what ebezzy said. Try multiplying the equations by a constant i.e a number so you can get either x or y to cancel when you add them.

    0.4(0.3x-0.2y)=4 = (0.12x-0.8y)= 1.6 -0.3(0.4y+0.5y)=1= (-0.12-0.15y)=-0.30 -.95y=1.3 so y = -1.3 now solve for x
