Explicación paso a paso:

a) 12 = 6 + X

  -X = 6 - 12

  -X = -6/-

    X = 6

b) X - 7 =3

   X = 3 + 7

   X = 10

c) 6X - 2X = 8

   4X = 8/4

   X = 2

d) 36 = t × 4

   t × 4 = 36

   t = 36/4

   t = 9

e) 2(b + 2) + 5(b - 3) = 3

   2b + 4 + 5b - 15 = 3

   2b + 5b = 3 - 4 + 15

   7b = -1 +15

   7b = 14/7

    b = 2

f) 6r + 12r - 9 - 8r + 10 + r = 12

  6r + 12r - 8r + r = 12 + 9 - 10

  18r - 8r + r = 12 + 9 - 10

  10r + r = 12 + 9 - 10

  11r = 12 + 9 - 10

  11r = 21 - 10

  11r = 11/11

   r = 1

g) 50 = 2X + 8

   2X + 8 = 50

   2X = 50 - 8

   2X = 42/2

    X = 21
