14 = 31.7 - 3x    

-17.7 = -3x              <---- I subtracted 31.7 from both sides

5.9 = x       <---- I divided both sides by -3

14 = 31.7 - 3x

First we want to isolate the x term.

(Subtraction property of equality)
14 - 31.7 = -17.7

-17.7 = -3x

Now we use the division property of equality to isolate the x variable.

(-17.7 ÷ -3 = 5.9   Two negative equals a positive)

x = 5.9
