When you face tough linear equations in your GCSE exams, there are some helpful tips that can make things easier.
Isolate the Variable: First, you want to get all the terms with the variable on one side of the equation. For example, if you have something like (3x + 5 = 2x - 7), subtract (2x) from both sides to change it to (x + 5 = -7).
Combine Like Terms: Remember to combine any like terms. This helps clear up the equation and makes it simpler to see your next steps.
Use Inverse Operations: If you need to get rid of a number, do the opposite operation. For example, with (x + 5 = -7), you can subtract 5 from both sides to get (x = -12).
Check Your Work: After you find a solution, put it back into the original equation to see if it works. This may take a little extra time, but it helps you catch mistakes.
By using these tips, you can feel more sure of yourself when solving tricky linear equations. And remember, practice makes perfect!
