Answer 1

a+r+g=4860
a+r=2600
r+g=2500

2600+g=4860
g=4860-2600
g=2260

a+2500=4860
a=4860-2500
a=2360

2360+r+2260=4860
r=4860-2360-2260
r=240

proba    a+r+g=2360+240+2260=4860

Answer 2

a+r+g=4860
a+r=2600
r+g=2500
2600+g=4860
g\4860-2600
g=2260

r+2260=2500
r=2500-2260
r=240

a+240=2600
a=2600-240
a=2360
