  1. Hey, try the problems.
    also be careful typing
    y-5/3=1

    which is y = 8/3

    is NOT

    (y-5)/3 = 1

    which is y = 8

    For #7, first, distribute (multiply) 4 with the stuff in the parenthesis, so (4*y) - (4*4) = 8.
    You should get 4y - 16 = 8. Then ADD 16 to both sides. 16 will disappear from the left side, but add to the right, so 4y = 8 +16. You should get 4y = 24.
    Divide both sides by 4 to get y by itself, so 4y/4 = 24/4. Then simplify to y = 6 since 24/4 = 6. Hope this helps!
