Answer:

x = -2

Explanation:

(   1 - 4x)/3 = 3      Multiply both sides by 3

       1 - 4x = 9      Subtract 1 from each side

           -4x = 8      Multiply each side by -1

            4x = -8     Divide each side by 4

              x = -2

===============

Check:

(1 – 4(-2))/3 = 3

      (1+8)/3 = 3

           9/3 = 3

              3 = 3
