Question

Solve the two step equation 14=31.7-3×

Answer 1

14 = 31.7 - 3x

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

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

Answer 2

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
