Solve for the following equation for z.

t=1/5(x-y+z)

T = 1/5(x - y + z)

First, let's get rid of the 1/5. To do this, you can multiply both sides by the reciprocal, or 5/1.

(5/1)T=[(5/1)1/5](x-y+z)
5T = x - y + z

Now subtract x from both sides.
5T - x = -y + z

Add y to both sides.
5T - x + y = z

So the answer is:
z = 5T - x + y

You're doing something i dont know how to do but search up on google slope calculator maybe that will get you there
