    3, 18

    Step-by-step explanation:

    To write an equation or an expression, define the variables.

    x is the first number.

    6x is the second number since it is 6 times the first.

    Add the expressions together to 21 to solve.

    x + 6x = 21

    7x = 21

    x=3

    The first number is 3. The second is 6*3 = 18.
