A video game system and several games cost $628 the cost of the games is 3 times the cost of the system find the cost of the system, and the games?

Games: $471; System: $157

s = cost of the system, and g = cost of the games

It is given that s+g = 628

and g=3*s

s+3*s = 628

4s = 628

s = 157

s+g = 628

157+g = 628

g = 628-157

g = 471
