Hi there,
Small and large packages = 8
Make small packages = x and large packages y
x + y = 8.......Eq(1)
3.5x + 5y = 31.......Eq(2)
Multiply Eq(1) by 3.5
3.5x + 3.5y = 28.......Eq(1)
3.5x + 5y = 31.........Eq(20
Subtract Eq(1) from Eq(2)
......1.5y = 3
.........y = 2
Substitute y = 2 into Eq(1)
x + y = 8
x + 2 = 8
x = 6
6 small parcels and 2 large parcels.
Hope this helps :-)
