Answer:

1) x = 7

2) x = 4

3) x = 1/9

Step-by-step explanation:

1) 3x +6 = 27

        -6     -6           Subtract 6 to both sides

   3x = 21                Then divide both sides by 3

     x = 7

2) 6x +3 = 27

         -3      -3         Subtract 3 to both sides

   6x = 24               Then divide both sides by 6

     x = 4

3) 27x +3 = 6

           -3   -3          Subtract 3 to both sides

   27x = 3                Then divide both sides by 27

       x = 3/27            Reduce

       x = 1/9
