What is the value of z in the equation 2(4z -9 -7) = 166 -46?
1 answer:
Answer:
A. 19
Step-by-step explanation:
2(4z -9 -7) = 166 -46
First combine like terms
2(4z -16) = 120
Divide each side by 2
2/2(4z -16) = 120/2
4z-16=60
Add 16 to each side
4z-16+16 = 60+16
4z = 76
Divide each side by 4
4z/4 = 76/4
z = 19
