b) 17x + 21 = 72

   17x = 72 - 21

    17x = 51

    x = 3

c) 5x + 2 = 17

    5x = 15

     x = 3

d)  2x + 4 = 20

    2x = 16

  x = 8

e)   3x - 3 = 24

    3x = 27

     x = 9

f) 6x - 12 = 12

  6x = 24

   x = 4

g) 9x - 20 = 7

   9x = 27

 x = 3

h) 14 + 6x = 56

     6x = 56 - 14

    6x = 42

    x = 7
