Solve for x in terms of y and z, assuming \(y\neq 3\): \(xy = 3x + 2y + z.\)
This is solving for x. :)
xy = 3x + 2y + z, right? So, we can divide both sides by y to get
x = (3x + 2y + z) / y :D Is that it? Do we need to do anything more?
xy = 3x + 2y + z
xy - 3x = 2y + z
x ( y - 3) = 2y + z
2y + z
x = _______
y - 3
