    the sum of two number is 35 and their difference is 1 . let,s start by calling the two numbers we are looking for x and y.

    The sum of x and y is 35. In other words, x plus y equals 35 and can be written as equation A:

    x + y = 35

    The difference between x and y is 1. In other words, x minus y equals 1 and can be written as equation B:

    x – y = 1

    Now solve equation B for x to get the revised equation B:

    x – y = 1

    x = 1 + y

    Then substitute x in equation A from the revised equation B and then solve for y:

    x + y = 35

    1 + y + y = 35

    1 + 2y = 35

    2y = 34

    y = 17

    Now we know y is 17. Which means that we can substitute y for 17 in equation A and solve for x:

    x + y = 35

    x + 17 = 35

    X = 18

    Summary: The sum of two numbers is 35 and their difference is 1. What are the two numbers? Answer: 18 and 17 as proven here:

    Sum: 18 + 17 = 35

    Difference: 18 – 17 = 1
