    Answer: 0=0

    Step-by-step explanation:

    First you want to solve for x

    2x+y=−4

    Step 1: Add -y to both sides.

    2x + y + −y =−4+ −y

    2x=−y−4

    Step 2: Divide both sides by 2.

    2x/2= -y-4/2

    x=-1/2y-2

    Then you want to plug in your answer for x into the equation so:

    2(-1/2y-2)+y=-4

    Step 1: Simplify both sides of the equation.

    2(-1/2y-2)+y=-4

    (2)(
    −1/
    2
    y)+(2)(−2)+y(Distribute)

    −y+−4+y=−4

    (−y+y)+(−4)=−4(Combine Like Terms)

    −4=−4

    −4=−4

    Step 2: Add 4 to both sides.

    −4+4=−4+4

    0=0.

    Sorry if this wasn’t the answer your looking for. If you need more help I suggest using Ma.th.Pa.pa calculator but with out the periods. Hope you have a good day 🙂
