We can put the two equations together with substitution, and we get
3x + 2y = 30
Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.

Answer:
Step-by-step explanation:
By using j, s ,h to represent the number of jerseys,shorts and hats respectively.
System of Equations:
j + s + h = 40
j = s + h
50j + 20s + 15h = 1350
(s + h) + s + h = 40
2s + 2h = 40
s + h = 20
s = 20 – h
50[(20 – h) + h] + 20(20 – h) + 15h = 1350
50(20) + 400 – 20h + 15h = 1350
1400 – 5h = 1350
5h = 50h
h = 10
s = 20 – 10
s = 10
j = 10 + 10
j = 20
20 jerseys, 10 shorts, 10 hats
