Checking Algebra Answers GCSE Maths
Checking your algebra answers is one of the easiest ways to avoid losing marks in GCSE Maths exams.
Substitute Your Answer Back In
If you solve an equation and get x = 5, substitute 5 back into the original equation to check it works.
Exam tip: GCSE examiners reward accurate methods. Checking can help you catch sign errors and arithmetic mistakes.
Common mistake: Some students only check the final line instead of checking against the original equation.
