    1.

    Step 1: Flip the equation.

    4x-6=y

    Step 2: Add 6 to both sides.

    4x-6+6=y+6

    4x=y+6

    Step 3: Divide both sides by 4.

    4x

    =

    y+6

    2.

    Step 1: Add 4y to both sides.

    5x-4y+4y=-9+4y

    5x=4y-9

    Step 2: Divide both sides by 5.

    5x

    =

    4y-9
