8z - 22 = 3(3z+11) - z

expand by using distributive property

8z - 22 = 9z + 33 - z

simplify

8z - 22 = 8z + 33

0 = 55

No solution

Hello!

First of all, let's undo the parentheses.

8z-22=9z+33-z

Now we add 22 to both sides.

8z=9z+55-z

Now we subtract add z to both sides.

9z=9z+55

We are left in a bit of a twist here. 9z cannot equal 9z plus something else. If you subtracted 9z from both sides, you would get 0=55, which is a false equation.

Therefore, there is no answer to this equation.

I hope this helps!
