Question 336053: Uhm, I don't even know if this is the right category for these problems.
1. v=1/6ab(x+y) and I have to solve for x....I don't know how to distribute the x+y.

2. v= pi*h^2(r-h/3) and I have to solve for r...once again, I don't know how to do it with the parenthesis.

You can put this solution on YOUR website!
v=1%2F%286ab%28x%2By%29%29
+6ab%28x%2By%29+=+1%2Fv
divide by 6ab on both sides
%28cross+%286ab%29%28x%2By%29%29*1%2Fcross%286ab%29 = 1%2F%286abv%29
+x%2By+=+1%2F%286abv%29
add -y to both sides
x%2By-y+=+%281%2F%286abv%29%29-y+
+x=+%281-6abvy%29%2F6abv
....
v= pi*h^2(r-h/3)
v%2F%28pi%2Ah%5E2%29+=+r-%28h%2F3%29
%28v%2F%28pi%2Ah%5E2%29%29%2Bh%2F3+=r
