How much money does Robert have (equation)

Answer :

kowaiikumo
Ed has x+100

(x+100)-20=5x

x+100-20=5x

x+80=5x subtract x from each side

x-x+80=5x-x

80=4x divide each side by 4

x=20 (amount that Robert has)

x+100=20+100=120 dollars (amount that Ed has)

120-20=5*20

100=100
I was gonna say do 100-80=20
20/5=16 so 16 is the answer
