12z-9-10z+3-8z=z-9+2z+10-10z

12 z - 9 - 10 z + 3 - 8 z = z - 9 + 2 z + 10 - 10 z

z = 7

Solution steps

12 z - 9 - 10 z + 3 - 8 z = z - 9 + 2 z + 10 - 10 z

Subtract

- 9 - 10 z

from both sides

12 z - 9 - 10 z + 3 - 8 z - (- 9 - 10 z) = z - 9 + 2 z + 10 - 10 z - (- 9 - 10 z)

Simplify

12 z + 3 - 8 z = z + 2 z + 10

Group like terms

12 z - 8 z + 3 = z + 2 z + 10
