    8 and 17

    Step-by-step explanation:

    Let x = 1st number

    y = 2nd number

    x = 2y+1

    x+y = 25

    Substitute into the second equation x=2y+1 for x

    x+y = 25

    (2y+1) + y = 25

    Combine like terms

    3y+1 = 25

    Subtract 1 from each side

    3y+1-1 = 25-1

    3y = 24

    Divide by 3 on each side

    3y/3 = 24/3

    y = 8

    x = 2y+1

    x = 2 (8) + 1

    x=17
