    5 and 20

    Step-by-step explanation:

    Let the numbers be x and y

    and x be the smaller number

    Then

    y+x=25 ... eqn (1) x2

    2y-3x=25 ... eqn (2) x1

    2y+2x=50

    2y-3x=25

    Subtract eqn 2 from 1

    then,

    5x=25

    x=5

    substitute the value of x in eqn 1

    y+5=25

    y=25-5

    y=20

    Therefore the numbers are 20 and 5

    The numbers are 5 and 20 respectively.

    Step-by-step explanation:

    Let two numbers are x and y.

    According to question-

    x + y = 25 ... (i)

    Given x is smaller number and y is larger number.

    then,

    2 y - 3 x = 25 ... (ii)

    To solve equation (i) and (ii) -

    Firstly multiply by 3 in equation (i) and then add in equation (ii) -

    3 x + 3 y = 75

    - 3 x + 2 y = 25

    5 y = 100

    y = 20

    Put y = 100 in equation (i) -

    We get,

    x = 25 - 20

    x = 5

    Therefore x = 5 and y = 20.
