    Answer:

    The answer to the first one is y=3/2x-27/2

    The answer to the second one is y=-3/5x+6/5

    Step-by-step explanation:

    1. 2y-3x=-27

    first, you want to add ‘3x’ to both sides.

    2y=3x-27

    then you want to divide ‘2’ from both sides. you do not want to use the ‘y’ because you want to keep the ‘y’ on its own side.

    y=3/2x-27/2

    2. 5y+3x=6

    First, you want to subtract ‘3x’ from both sides.

    5y=-3x+6

    Now, you want to divide ‘5’ from both sides.

    y=-3/5x+6/5
