Hi,
With these types of equations, always try to simplify both sides of the equation as it would be less work later on.
Therefore, 3x + 3x = 6x and 129 + 27 = 156. With this in mind, let's apply it to your problem:
6x + 156 = 180
Now subtract 156 from both sides of the equation to get:
6x = 24
Next, divide both sides by 6 to isolate for x alone and get:
x = 4 <=== FINAL ANSWER
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew
