    17 & 37

    Step-by-step explanation:

    Let x and 2x + 3 be the numbers.

    x + 2x + 3 = 54 \\ 3x = 54 - 3 \\ 3x = 51 \\  \frac{3x}{3}  =  \frac{51}{3}  \\ x = 17

    We have found one of the numbers! Let us get the other one by substitution.

    2x + 3 \\ = 2(17) + 3  \\  = 34 + 3 \\  = 37

    Let's check!

    17 + 37 = 54 \\ 54 = 54

    Correct!

    10 + 13

    Step-by-step explanation:

    23 minus 3 = 20

    20 divide by 2 = 10

    10 + 3 = 13

    So, 10 plus 13 = 23

    13 is 3 numbers more than 10

    10 and 13

    13 is 3 more than 10

    13 plus 10 is 23.

    A. Assign the two numbers unknown variables:

    Let one number equal (x)

    Let the second number equal (y)

    B. Create equations from the given information.

    Two numbers have a sum of 23:

    Equation 1. x + y = 23

    One number is 3 more than the other:

    Equation 2. x = 3 + y

    C. Substitute the value of (x) from Equation 2 into Equation 1.

    (3 + y) + y = 23

    3 + y + y = 23

    3 + 2y = 23 Subtract 3 from both sides.

    2y = 20 Divide both sides by 2.

    y = 10 Substitute y = 10 into either Equation 1 or 2 to find (x). Use Equation 2.

    x = 3 + 10 = 13

    x = 13

    answer:

    9 and 6

    why?

    3 is the difference between 9 and 6

    and also

    9 + 6 = 15
