Question 358597: Can somebody please help me with this equation, I solved it but, i don't know if it's right. This is the problem :
solve for z
y = xz + z - x
i came up with :
y = xz + z - x
y + x = xz + z
y + x \ x = 2z
y = 2z
y \ 2 = z
z = y \ 2
I really do not know if this is right but this is what I came up. So please can somebody help me.
I'm afraid you violated some algebra rules after the first step.
y = xz + z - x
Isolate all the terms that contain z on one side of the equation
(You did that correctly, but after that it was all incorrect):
y + x = xz + z
Factor out z on the side you isolated z terms on, which is the right
side in this case:
y + x = z(x + 1)
Divide both sides by (x + 1)
y + x z(x + 1)
----- = ----------
x + 1 (x + 1)
Cancel the (x + 1)'s on the right
y + x z(x + 1)
----- = ----------
x + 1 (x + 1)
y + x
----- = z
x + 1
That's the final answer. Don't try to go any further.
