Answer:
Dan has $7 and Julio has $12
Step-by-step explanation:
Julio = x
Dan = y
They both have a total of $19:
x + y = 19
Julio has 5 more dollars than Dan:
(Therefore Dan would need 5 more dollars to catch up to what Julio has)
y + 5 = x
We now plug in one equation into the other and get:
y + (y+5) = 19
2y+5 = 19
2y = 14
y = 7
Plug in Dan's amount into the initial equation and we get:
7+5 = x
x =12
