Answer provided by our tutors
let
r = the number of cars Rodney sold in March
g = the number of cars Greg sold in March
In March, Rodney sold twice as many cars as Greg
r = 2g
In April, Rodney sold 5 fewer cars than he did in March, While Greg sold 3 more cars than he did in March and they sold the same number of cars in April:
r - 5 = g + 3
by solving the system of equations:
r = 2g
r - 5 = g + 3
we find
r = 16 cars
g = 8 cars
