Answer provided by our tutors
let
x = the number of players that Essie sold
y = the number of players that Ruby sold
Last month Essie sold 35 less blu-ray players than Ruby:
x = y - 35
Together they sold 145:
x + y = 145
by solving the system of equations:
x = y - 35
x + y = 145
we find:
x = 55 blu-Ray players
y = 90 blu-Ray players
