In this guide, we'll walk through 2x + 5 = 15 (Step - by - Step Guide) step by step. Whether you're revising for an exam or practising linear equations, this clear walkthrough will help you understand not just the answer, but the reasoning behind every step.
See the step-by-step solution above for the complete answer.
Step 1: Identify the variable and the operations applied to it.
Step 2: Apply inverse operations to isolate the variable.
Step 3: Simplify both sides of the equation.
Step 4: The solution is found by completing the steps above.
Linear equations follow a simple principle: whatever you do to one side, you must do to the other. This keeps the equation balanced, like a scale. By performing inverse operations (subtraction undoes addition, division undoes multiplication), we systematically peel away layers until x stands alone.
Linear Equations is a fundamental concept in math. Mastering it gives you a strong foundation for more advanced topics.
❌ Mistake 1: Forgetting to apply the same operation to both sides of the equation.
❌ Mistake 2: Making sign errors when moving terms across the equals sign.
❌ Mistake 3: Not simplifying the final answer completely.
