Remember you can do anything to an equation as long as you do it to both sides
a=age

500 reduced by 2 times a is equal to 388

500-2a=388
minus 500 both sides
-2a=-112
divide both sides by -2
a=56

you are 56

Z divided by 3-2z + 4(z-8) when z = 18 A. -122 B. 6 C. -66 D. 10

murzikaleks [220]

Everywhere you see z, replace the letter with 18.

z/[(3- 2z)] + 4(z - 8)

18/[(3 - 2(18))] + 4(18 - 8)

You finish.
