Question

Solve for z.
5z + 8 = 3z + 16
z = [?]
Z

Answer 1

z = 4

Explanation:

5z + 8 = 3z + 16

5z = 3z + 16 - 8

5z = 3z + 8

5z - 3z = 8

2z = 8

z = 4

check equation (unnecessary)

5(4) + 8 = 3(4) + 16

20 + 8 = 12 + 16

28 = 28

Answer 2

z = 4

Explanation:

5z + 8 = 3z + 16 ( subtract 3z from both sides )

2z + 8 = 16 ( subtract 8 from both sides )

2z = 8 ( divide both sides by 2 )

z = 4
