Answer:
2 solutions 3 (-2 z + 1) and 3 (1 - 2 z)
Step-by-step explanation:
Left side
Simplify the following:
-8 z + 3 + 2 z
Grouping like terms, -8 z + 3 + 2 z = (2 z - 8 z) + 3:
(2 z - 8 z) + 3
2 z - 8 z = -6 z:
-6 z + 3
Factor 3 out of -6 z + 3:
Answer: 3 (-2 z + 1)
____________________________________
Right side
Simplify the following:
-6 z - 4 + 7
Grouping like terms, -6 z - 4 + 7 = (7 - 4) - 6 z:
(7 - 4) - 6 z
7 - 4 = 3:
3 - 6 z
Factor 3 out of 3 - 6 z:
Answer: 3 (1 - 2 z)
