Answer provided by our tutors
let
x = the number of tie-dyed t-shirts
y = the number of silk t-shirts
Last week at a festival a man sold 4 times as many tie-dyed t-shirts as silk t-shirts
x = 4y
He sold 195 shirts all together
x + y = 195
by solving the system of equations
x = 4y
x + y = 195
we find
x = 156 tie-dyed t-shirts
y = 39 silk t-shirts
