    Label your numbers (I'm picking x and y)

    x+y=35

    2x=5y

    find the relationship between your numbers

    x=35-y

    apply this to the other equation

    2 (35-y) = 5y

    now simplify to find y

    70-2y=5y

    70=7y

    y=70/7=10

    now apply your newly found y to find x

    x+10=35

    x=25

    check your answers

    2 (25) = 5 (10)

    50=50

    so our first number x is 25 and our second number y is 10
