    Step-by-step explanation:

    99x+101y=499—–(1)

    101x+99y=501——(2)

    Since the LCM of 99 and 101 is 9999, we need multiply (1) by

    101 and (2) by 99,

    9999x+10201y=50399——(3)

    9999x+9801y=49599——(4)

    Subtracting (4) from (3),

    400y=800

    ➡y=2

    Substituting y=2 in (1),

    99x+101(2)=499

    99x=499-202

    99x=297

    ➡x=3

    Hence,

    ↪x=3

    ↪y=2
