let the smallest number be x and the largest be y
according to first equation
x-y=3
x=3+y
according to second equation
2x+y=19
2(3+y)+y=19
6+2y+y=19
3y=13
y=13/3
x=3+y
x=3+(13/3)
x=9+13/3
x=22/3
according to first equation
x-y=3
x=3+y
according to second equation
2x+y=19
2(3+y)+y=19
6+2y+y=19
3y=13
y=13/3
x=3+y
x=3+(13/3)
