Question

If 6z +4= 8z, then 12z =
A 1
B 4
C 12
D 24

Answer 1

The answer is = C

Explanation:

`6z + 4 = 8z \\ 4 = 8z - 4z = 4z \\ 4 = 4z \\ z = 1 \\ 12z = 12`

Answer 2

Answer: D is the correct option , answer is 24

Explanation:

Since 8z = 6z + 4

Combine like terms

8z -6z = 4

2z = 4

Divide both sides by 2 to get the value of z

z = 4/2

z = 2

Since z is 2, 12z will be written as 12(2)= 12 x 2= 24
