Answer provided by our tutors
let
x = the bill for the first shop
y = the bill for the second shop
the telephone bill for the first shop was $530 less than three times the telephone bill for the second shop
x = 3y - 530
the total telephone expense for both shops was $2574
x + y = 2574
by solving the system of equations
x = 3y - 530
x + y = 2574
we find
x = $1,798
y = $776
