Answer provided by our tutors
let
x = the cost of the system
y = the cost of the games
all together they cost $672
x + y = 672
the cost of the games is 3 times as much as the cost of the system
y = 3*x
by solving the system of equations
y = 3*x
x + y = 672
we find
x = $168
y = $504
the cost of the system is $168.
the cost of the games is $504.
