Answer:
2(4 + 2z) = 8 + 4z
or
2(4 + 2z) = 0
z = -2
Step-by-step explanation:
How to solve:
2(4 + 2z)
Distribute:
2(4 + 2z)
2(4) + 2(2z)
Multiply:
2(4) + 2(2z)
8 + 4z
8 + 4z is the simplified expression.
How to solve:
2(4 + 2z) = 0
Distribute:
2(4 + 2z) = 0
2(4) + 2(2z) = 0
Multiply:
2(4) + 2(2z) = 0
8 + 4z = 0
Subtract 8 on both sides:
8 + 4z = 0
-8 -8
4z = -8
Divide by 4 on both sides:
4z = -8
/4 /4
z = -2
z = -2 is the answer if 0 is on the other side of the equal sign
