Now combine like terms on the left:
$ 4x - 5 = 2x + 5 $
Subtract $ 2x $ from both sides to gather $ x $-terms on one side:
$ 4x - 2x - 5 = 5 $
$ 2x - 5 = 5 $
Add 5 to both sides to isolate the variable expression:
$ 2x = 10 $
Finally, divide both sides by 2:
$ x = 5 $
Every step reinforces a methodical approach—useful not only for equations but for any structured problem-solving journey. This clarity appeals to readers seeking confidence and practicality, not just answers.
