Systems of Equations

-x+4y = 8
2x-3y = -16

x= -17.6
y= -2.4

Is this right?

    No, it is not right. How did you get that?

    Convert the first equation (by doubling both sides) to:
    -2x + 8y = 16
    Put it above
    2x - 3y = -16
    and add both sides.

    You get 5y = 0

    It is pretty clear what y must be.
