4 0

2(4z - 6 - 6) = 170 - 46

2(4z - 12) = 124 |use distributive property: a(b - c) = ab - ac

8z - 24 = 124 |add 24 to both sides

8z = 148 |divide both sides by 8

z = 18.5

Answer:

Step 4, x = 3

Step-by-step explanation:

Step 4 was wrong, instead of 6x = 6, it should be 6x = 18. They shoudl've added 6 to both sides instead of subtracting 6 as ur trying to cancel out the 6 on the left side of the equation. So:

6x = 18

x = 3
