If it's not what You are looking for type in the equation solver your own equation and let us solve it.

8z-12=3(3z+11)-z

We move all terms to the left:

8z-12-(3(3z+11)-z)=0

We calculate terms in parentheses: -(3(3z+11)-z), so:We get rid of parentheses

3(3z+11)-z

We add all the numbers together, and all the variables

-1z+3(3z+11)

We multiply parentheses

-1z+9z+33

We add all the numbers together, and all the variables

8z+33

Back to the equation:

-(8z+33)

8z-8z-33-12=0

We add all the numbers together, and all the variables

-45!=0
