Answer: z = -4
Explanation:
Simplifying
5z + -8 = -28
Reorder the terms:
-8 + 5z = -28
Solving
-8 + 5z = -28
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '8' to each side of the equation.
-8 + 8 + 5z = -28 + 8
Combine like terms: -8 + 8 = 0
0 + 5z = -28 + 8
5z = -28 + 8
Combine like terms: -28 + 8 = -20
5z = -20
Divide each side by '5'.
z = -4
Simplifying
z = -4 Hope this helps !
