When solving linear equations, Year 10 students often make mistakes that can hurt their understanding and performance. Here are some common errors to watch out for:
Ignoring BODMAS/BIDMAS Rules:
Students sometimes forget the order of operations. This can lead to wrong answers. For example, in the equation (3 + 2x = 11), some may add before they isolate (x). This can confuse them.
Mistakes with Distribution:
A common problem is not distributing terms properly when using the distributive property. For example, in (2(3 + x)), students might mistakenly simplify it to (2 \cdot 3 + x). The correct way is (2 \cdot 3 + 2 \cdot x), which equals (6 + 2x).
Incorrectly Combining Like Terms:
Some students find it hard to combine like terms. For example, in (5x + 3x), a common mistake is to write it as (8xy). The right way to write it is (8x).
Not Balancing Equations Properly:
It’s important to do the same operation on both sides of the equation. If students don’t remember this, they can end up with wrong answers. For instance, when solving (x + 4 = 10), some might write (x = 10 - 4) without keeping the equation balanced.
By being aware of these common mistakes, students can become more accurate and confident when solving linear equations.
