    x=

    -49/4y-20

    Step-by-step explanation:

    Let's solve for x.

    -4x-49y-80=0

    Step 1: Add 49y to both sides.

    -4x-49y-80+49y=0+49y

    -4x-80=49y

    Step 2: Add 80 to both sides.

    -4x-80+80=49y+80

    -4x=49y+80

    Step 3: Divide both sides by - 4.

    -4x

    -4

    =

    49y+80

    -4

    x=

    -49

    4

    y-20
