2(4z − 6 − 6) = 170 − 46     First simplify things by collecting like terms doing the subtractions on the R and L

2 (4z -12) = 124                  Now distrib prop on left

8z - 24 = 124                       Add 24 to both side

8z = 148                             Divide both sides by 8 to find z =

Oh Now I see thanks for that I though I just had to use one of the tweleves and add it to the 124. So I kept getting seventeen for an answer.
