    x = 17

    Step-by-step explanation:

    Let 'x' be the bigger number

    'y' be the smaller number

    x + y = 27

    or x = 27 - y --equation1

    x - y = 7 --equation 2

    Substitute equation 1 to 2

    27 - y - y = 7

    -y-y = 7 - 27

    -2y = -20

    y = 10

    Substitute it to equation 1

    x = 27 - y

    x = 27 - 10

    x = 17

    Its 20. As you can see 20 + 7=27 or 27-7=20

    The bigger number is 20 because 27- 7= 20 so 20+7=27
