    The value of two numbers is x=49 and y=26 and the corresponding equation for the given condition is x + y = 75

    Explanation:

    Given:

    Sum of two numbers is 75

    One number is 23 more than other

    To find:

    Frame the equation for the above condition and find the value of two numbers.

    Solution:

    From the given we know that the sum of two numbers is 75

    Let x and y be the numbers, such that the equation is framed as

    x + y = 75

    And we also know that one number is 23 more than other, so we can say either x or y has a greater one

    Here I say x is 23 more than y such that,

    x=23+y

    Substitute the value of x in the equation and we know

    x + y=75 and x=23+y we get,

    23+y+y=75

    23+2y=75

    2y=75-23

    2y=52

    y=26

    Since x=23+y as already stated we get as

    x=23+26=49

    Result:

    Thus the equation for the above given conditions is x + y = 75 and the values of two number is 49 and 26
