Solve for z when 4x + 10yz = 0

solve for z if y² + 3yz - 8z - 4x = 0?

Do I have to solve all of the variables in order to get z?

Hi,

You just solve for z treating the other variables and numbers as symbols. For example in the first problem add -4x to each side to get

10yz = - 4x

Next divide both sides by 10y to get

z = ^{- 4x}/_10y

Now try the second problem.
