0.3x-0.2y=4
0.4x+0.5y=-55/17

  • Math please help asap -

    1st one times 5, 2nd one times 2

    1.5x - y = 20
    .8x + y = -110/17

    add them
    2.3x = 230/17
    x = 100/17

    plug this back into 1.5x - y = 20
    1.5(100/17) - y = 20
    -y = 20 - 150/17
    y = -190/17

    weird equations, weird solutions, but they are right, I checked them
