i am two numbers,
the sum of my numbers is 1000,
the diffrence between my two numbers is 100

  • Math problems -

    a=first number

    b=second number

    a+b=1000

    a=1000-b

    a-b=100

    1000-b-b=100

    1000-2b=100

    1000-100=2b

    2b=900 Divide with 2

    b=450

    a=1000-b

    a=1000-450

    a=550

    a+b=550+450=1000

    a-b=550-450=100
