Answer:

The value of y is 2.

Step-by-step explanation:

1/3 ( y + 7 ) = 3 ( y - 1 )          Distribute

1/3y + 7/3   = 3y - 3              Subtract 1/3y on both sides

          7/3   = 2 2/3y - 3       Add 3 on both sides

          5 1/3 = 2 2/3 y           Divide 2 2/3 on both sides

               2  = y
