Answer 2

Answer:

Simplifying

8z + -24 = 4z

Reorder the terms:

-24 + 8z = 4z

Solving

-24 + 8z = 4z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '-4z' to each side of the equation.

-24 + 8z + -4z = 4z + -4z

Combine like terms: 8z + -4z = 4z

-24 + 4z = 4z + -4z

Combine like terms: 4z + -4z = 0

-24 + 4z = 0

Add '24' to each side of the equation.

-24 + 24 + 4z = 0 + 24

Combine like terms: -24 + 24 = 0

0 + 4z = 0 + 24

4z = 0 + 24

Combine like terms: 0 + 24 = 24

4z = 24

Divide each side by '4'.

z = 6

Simplifying

z = 6
