12(z+1)-5(z-1)=3(z-1)+3(z-2)

Solution for 12(z+1)-5(z-1)=3(z-1)+3(z-2) equation:

12(z+1)-5(z-1)=3(z-1)+3(z-2)

We move all terms to the left:

12(z+1)-5(z-1)-(3(z-1)+3(z-2))=0

We multiply parentheses

12z-5z-(3(z-1)+3(z-2))+12+5=0


We calculate terms in parentheses: -(3(z-1)+3(z-2)), so:

3(z-1)+3(z-2)

We multiply parentheses

3z+3z-3-6

We add all the numbers together, and all the variables

6z-9
