  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
