    Let x = the lesser number.

    Equation:

    x + 2x + 7 = 22

    3x = 15

    x = 5

    Answer: 5 is the lesser number. The other number is 2 * 5 + 7 or, 17. They total 22.

    5 is one of the numbers.

    Let x be one number.

    Let 2x + 7 be the other number.

    The sum is 22:

    x + 2x + 7 = 22

    3x + 7 = 22

    3x = 22 - 7

    3x = 15

    x = 15/3

    x = 5

    Answer:One of the numbers is 5 (the other is 17).

    The answer to the title question is YES. Good thing I know I got the answer correctly.

    For the second question, the solution is:

    If x=7+2y and x+y=22

    Then putting them together would be:

    7+2y+y=22

    2y+y=22-7

    3y=15

    y=15/3

    y=5

    And going back to the given:

    x=7+2y

    x=7+2(5)

    x=7+10

    x=17

    Which gives us the answer as either

    5 or 17.

    Let numbers be a and b.  You are told: a - 7 = 2b 

    ALSO a + b = 22 (or a = 22 - b)

    Substitute and solve for b

    22 - b - 7 = 2b,   gives 15 = 3b

    So: b= 5,  (AND as a check a = 17)

    Let the number be 2x and so if 2x+7 = 22 then 2x = 15

    One number is one-third of the result of 22 less 7, so that would be 5.

    Source(s): Providing both numbers is technically an incorrect answer to "What is one of the numbers?"

    Let the number be 'n'

    #1 = n

    #2 = 2n+7

    n + 2n + 7 = 22

    3n + 7 = 22

    3n = 15

    n = 5

    2n + 7 = 17

    I'll go with 17 and 5
