What is the solution of 3x = 9?

**Possible Answers:**

1/3

3

–3

–6

6

**Correct answer:**

3

When solving a one step equation like this, we do the inverse operation to isolate the variable. In this case, we have 3x = 9, so we divide both sides by 3 to get x = 3.

3x = 9

(3x)/3 = (9)/3

x = 3
