Combine like terms:

Key Insights

  • The terms 2x and 12x are like terms since both contain x.
  • Add them:
     2x + 12x = 14x

So the equation becomes:

14x - 27 = 16


Step 1: Isolate the Variable Term

Final Thoughts

To isolate 14x, add 27 to both sides of the equation to eliminate the constant term on the left:
