so let's call this 2 numbers "a" and "b"

their sum is 81   =>   a  +  b = 81

twice one and three times the other is 62.
        2a                3b                              = 62


so
a  + b = 81
2a + 3b = 62

so, there :)

        2a       -        3b                              = 62


so
a  + b = 81
2a - 3b = 62

so, there :)
