When you work with standard form linear equations, like (Ax + By = C), there are some common mistakes that people often make. Here are a few to watch out for:
Forgetting to Simplify: Sometimes, we forget to make the equation simpler. It's important to ensure that numbers (A), (B), and (C) do not have any common factors, except for 1. Also, (A) should be a positive number or zero.
Missing Coefficients: Occasionally, students ignore some coefficients. For example, in the equation (y = 2), we can rewrite it in standard form as (0x + y = 2).
Sign Errors: Be careful about signs when changing the equation around. If you accidentally flip a sign, it can cause you to get the wrong answer.
Not Identifying Integers: Remember that (A), (B), and (C) should all be whole numbers, which we call integers.
If you keep these tips in mind, you can avoid some common mistakes!
