Question #e37ed

Answer 1

I found:
Andre`=R146`
Bob`=R106`

Explanation:

Call:
`x` money of Andre;
`y` money of Bob;
You can build a system of two equations "translating" into maths your statements:

`x-20=y+20`
`x+22=2(y-22)`

Rearranging:
`{x-y=40`
`{x-2y=-66`
from the first one you have: `x=40+y` substitute for `x` into the second:
`40+y-2y=-66`
so: `y=106` substitute back to find `x`:
`x=40+106=146`
