R + A + G = 95.....lol...rag
G = 3A
A = R - 10
G = 3(R - 10)...G = 3R - 30
R + A + G = 95
R + (R - 10) + (3R - 30) = 95
5R - 40 = 95
5R = 95 + 40
5R = 135
R = 135/5
R = 27 <===Raini sent 27
A = R - 10
A = 27 - 10
A = 17 <===Austin sent 17
G = 3R - 30
G = 3(27) - 30
G = 81 - 30
G = 51 <==Goran sent 51
