Answer: 226 T-shirts and 21 shorts
Explanation:
Let the number of T-shirts be x and the number of shorts be y
Hence,
2(x)+4(y)=536
Divide both parts of the equation by 2:
x+2y=268
x+y+y=268
(x+y)+y=268
(x+y)+y-(x+y)=268-(x+y)
y=268-(x+y) (1)
x+y=247 (2)
Substitute equation (2) into equation (1):
y=268-247
y=21
Hence,
x+21=247
x+21-21=247-21
x=226
