Solve for z: 5(2z-7) = -2z + 7

A. z = 7/2
B. z= 21/4
C. z= -7/2
D. z= - 7/3

A. z = 7/2

Step-by-step explanation:

First, distribute the 5 into 2z and 7 to get 10z - 35 for the left side and the right side should be the same.  Add 2z on both sides to get to this equation 12z - 35 = 7.  Add 35 on both sides to get 12z = 42.  Divide 12 on both sides, since it is an improper whole number, the fraction would be left as 42/12.  However, both numbers can be divisible by 6 leaving your z value as 7/2.

The answer is
