Solving Equations with Variables on Both Sides


🧮 Example:


Solve:

3x + 4 = 2x + 9


---


✏️ Step 1: Move variables to one side


Subtract 2x from both sides:

3x - 2x + 4 = 2x - 2x + 9

x + 4 = 9


---


✏️ Step 2: Move constants to the other side


Subtract 4 from both sides:

x + 4 - 4 = 9 - 4

x = 5


---


✅ Final Answer:


x = 5


---


📝 Quick Tip:


Always move all the x terms to one side and the numbers to the other before solving. Then simplify step-by-step.
