Answer:
The solution set is {-7, 7}.
Step-by-step explanation:
He was half right .There are 2 solution d = -7 and d = 7.
The first step for solving this equation is to determine the defined range.

, z ≠ 0
Move the expression

to the left side of the equation and change its sign.

-

=

Now we need to write all numerators above the least common denominator of 8z. This will change the equation to the following:

=

Simplify the equation using cross multiplication.
8 = -56z
Switch the sides of the equation.
-56z = 8
Divide both sides of the equation by -56.

, z ≠ 0
Lastly,, check if the solution is in the defined range to get your final answer.
