Answer:

x = 5

Step-by-step explanation:

6 = 3x - 9

If you add 9 to both sides 6 + 9 = 3x - 9 + 9. You would get the equation 15 = 3x because adding 9 to both sides cancels out the 9 on the right side of the equation. Then you would divide by 3 on both sides 15/3 = 3x/3 which would give you 5 = x your answer
