SOLUTION: 1/3(s-2)=s+4

1/3(s - 2) = s + 4

Clear of fractions by multiplying both 
sides by LCD = 3


3[1/3(s - 2)] = 3(s + 4)

Cancel the 3 and the 1/3

1
3[1/3(s - 2)] = 3(s + 4)
    1

       s - 2 = 3(s + 4)

Distribute the right side:

       s - 2 = 3s + 12

Add 2 to both sides

           s = 3s + 14

Add -3s to both sides

         -2s = 14

Divide both sides by -2

           s = -7
