    x=-2y+2

    Step-by-step explanation:

    Step 1: Add - 2y to both sides.

    x+2y+-2y=2+-2y

    x=-2y+2

    Answer:

    x=-2y+2

    Step 1: Add - 4y to both sides.

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

    2x=-4y-8

    Step 2: Divide both sides by 2.

    2x/2 = - 4y-8/2

    x=-2y-4

    Answer:

    x=-2y-4
