also be careful typing
y-5/3=1
which is y = 8/3
is NOT
(y-5)/3 = 1
which is y = 8

i swar they are correct!!!
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!
