Answer:

Step-by-step explanation:

andi +10 = charley

and in 4 years

2*andi = charley +4

so

2*andi -4 = charley

now since we have  charley as the indepentdent on each equation

set those parts equal to each other

andi + 10 = 2*andi -4

and + 14 = 2*andi

14 = andi

so andi is 14

charley is 24

In the present, Charley is 16 and Andi is 6.

Explanation: After 4 years Charley will be 20 and Andi will be 10.
Charley is 20 in the future Andi is 10. Therefore, Charley is in the “twice as old as Andi”category.

Answer: Charley is 16 and Andi is 6
