    Z = 2

    Step-by-step explanation:

    First, distribute the terms on the left side of the equation.

    3 (3y - 6) = 7y - 18 + Zy

    9y-18=7y-18+Zy, Next add 18 to both sides

    9y = 7y+Zy, Subtract 7y from both sides

    2y = Zy, Divide both sides by y

    2 = Z, Z=2

    Answer: y = 0/-z+2

    Step-by-step explanation:

    3 (3y-6) = 7y-18+zy

    Step 1:

    9y-18+-yz=yz+7y-18+-yz

    -yz+9y-18=7y-18

    Step 2:

    -yz+9y-18+-7y=7y-18+-7y

    -yz+2y-18=-18

    Step 3:

    -yz+2y-18+18=-18+18

    -yz+2y=0

    Step 4:

    y (-z+2) = 0

    Step 5:

    y (-z+2)

    -z+2

    =

    0 / -z+2
