number of short-sleeved shirts --- x

number of long-sleeved shirts --- 63-x

15x +22(63-x) = 1134

15x + 1386 - 22x = 1134

-7x = -252

x = 36

so 36 short-sleeved and 27 longsleeved shirts

Short shirt x

Long shirt y

x + y = 63

15x + 22y = 1134

substitute x = 63-y

15(63-y) + 22y = 1134

945 -15y + 22y = 1134

7y = 189

y =27

x = 36

short-sleeved shirts : 27

Long-sleeved shirts: 36
