Checking if your answers to linear equations are correct can seem tough for Year 10 students. Here are some common problems you might face:
Difficult Math Operations: You might find it hard to do the math needed to check your answers, especially with fractions or decimals.
Confusing Solutions: It can be tricky to understand what your answer really means and how it works with the original equation.
Simple Mistakes: Sometimes, small errors happen, like reading the equation wrong or making math errors. These can lead to wrong conclusions about whether your answer is right.
But don’t worry! Here’s a simple way to make it easier:
Plug In the Answer: Put the answer you found back into the original equation. For instance, if the equation is (2x + 3 = 11) and you found that (x = 4), just replace (x) with (4) in the equation.
Check Both Sides: After replacing the variable, see if both sides of the equation are the same. Using our example, check if (2(4) + 3 = 11).
Try Different Methods: If you’re unsure about your answer, try solving the equation again in a different way. You can use graphing or balancing to check your work.
By being patient and careful, you can build your confidence in solving and checking linear equations!
