Question 998959: solve 3(x+y)=z for x
AND (I'm sorry I put two, but theres a question limit and i have many more questions)
V=1/3(3.14)r^3h for h
help, please?

I know this is a stretch and I so understand if two questions is enough, but if you have time maybe help also with
2a+3b=10 for b
THANK YOU THANK YOU THANK YOU!!

solve 3%28x%2By%29=z for x
3x%2B3y=z
3x%2B3y-3y=z-3y
3x=z-3y
x=%28z-3y%29%2F3



V=%281%2F3%29%283.14%29r%5E3h for h
V=%281%2F3%29%283.14%29r%5E3h
V=%28%283.14%29r%5E3h%29%2F3
3V=%283.14%29r%5E3h
3V%2F%283.14r%5E3%29=h or
h=3V%2F%283.14r%5E3%29


2a%2B3b=10 for b+
3b=10-2a
b=%2810-2a%29%2F3
