Question 1172831: Trevor and Marissa together have 26 T-shirts to sell. If Marissa has 6 fewer T-shirts than Trevor, find how many T-shirts Trevor has. Use x as your variable.
x + y = 26 (1) (x = # of T-shirts Trevor has to sell)
x - y = 6 (2)
Add the equations and get
2x = 26 + 6 = 32; x = 32/6 = 16.
Then from equation (1) y = 26-16 = 10.
ANSWER. Trevor has 16 T-shirts; Marissda has 10.
