-1=5-z-z
--------
Get the z on one side of the equal sign by itself.
Combine terms.
-1 = 5 - 2z
Subtract 5 from both sides
-6 = -2z
Divide by -2
3 = z
That's all.

-1=5-z-z Start with the given equation.


-1=-2z%2B5 Combine like terms on the right side.


-1-5=-2z Subtract 5 from both sides.


-6=-2z Combine like terms.


-2z=-6 Rearrange the equation.


z=%28-6%29%2F%28-2%29 Divide both sides by -2 to isolate z.


z=3 Reduce.

Answer:

So the answer is z=3
