7z-18=-12z+4z-11+z
Combine 12z and -5z to get 7z.
7z-18=-8z-11+z
Combine -12z and 4z to get -8z.
7z-18=-7z-11
Combine -8z and z to get -7z.
7z-18+7z=-11
Add 7z to both sides.
14z-18=-11
Combine 7z and 7z to get 14z.
14z=-11+18
Add 18 to both sides.
14z=7
Add -11 and 18 to get 7.
z=\frac{7}{14}
Divide both sides by 14.
z=\frac{1}{2}
Reduce the fraction \frac{7}{14} to lowest terms by extracting and canceling out 7.
