    Step-by-step explanation:

    6 times the number is 6x.

    7 times the number is 7x.

    6 times the number plus 7 times the number is equal to 6x + 7x which is equal to 13x.

    for example:

    let x = 15

    6x = 6 * 15 = 90

    7x = 7 * 15 = 105

    6x + 7x = 6 * 15 + 7 * 15 = 90 + 105 = 195
