    The bigger number=(9+5)/2=7

    The smaller number=(9-5)/2=2.

    Suppose the numbers are A and B.

    A + B = 9 and A - B = 5

    (A + B) + (A - B) = 9 + 5

    therefore 2A = 14, so A = 7, and B = 7 - 5 = 2

    The numbers are N and 9-N.

    (9-N) - N = 5

    9 -2N = 5

    4 = 2N

    N = 2

    9-N  = 7.

    In a column, Write down all the number pairs from 1 to 8 that add up to nine.

    Put the largest number first. 

    Subtract each pair of numbers and when you find a number where the answer is 5 that is your answer.
