Okay, so you've solved a linear equation. Shiok! But hold on a second, don't submit that paper just yet! In Singapore, we believe in kiasi (afraid to lose), and that extends to ensuring our answers are correct. Here's your checklist for verifying solutions, Singapore style:
The Substitution Test: This is the confirm plus chop method. Take the value you found for 'x' (or whatever variable you're dealing with) and plug it back into the original equation. Does the left-hand side (LHS) equal the right-hand side (RHS)? If yes, hooray! You've got it right. If not, aiyo, back to the drawing board.
Double-Check Your Working: Sometimes, the simplest mistakes can trip us up. Go through your steps again, carefully. Did you accidentally add instead of subtract? Did you forget to distribute a negative sign? These little gremlins can sabotage your efforts.
Use a Calculator (Wisely): Calculators are your friend, but they're not a substitute for understanding. Use them to verify your arithmetic, especially with decimals or fractions. But remember, show your working! Examiners in Singapore want to see that you understand the process, not just that you can punch numbers into a machine.
Consider the Context: Does your answer make sense in the real world? If you're solving a problem about the number of students in a class, and you get a negative answer, something's definitely wrong.
Practice, Practice, Practice: The more you practice, the more comfortable you'll become with solving and verifying linear equations. It's like riding a bicycle; the more you do it, the easier it gets.
Let's take a quick detour to understand the building blocks of linear equations: algebraic expressions and equations.
The key difference? Equations can be solved to find the value of the variable, while expressions can only be simplified.
