Question
notation check: simplify 23x + 26x by collecting like terms. Show your working one step at a time.
Answer
The final answer is 49x. Start with 23x + 26x. The terms are like terms because both contain x. Add the coefficients 23 and 26. 49x
Explanation
exam warm-up keeps the canonical answer 49x fixed before the model answer is written, so the worked solution and final answer agree.
Common mistake
Identities and algebraic proof common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Use algebra to show that expressions are equivalent and to support or construct mathematical arguments..
Show the method first, then give the final answer in the required form. Apply this directly to Identities and algebraic proof.
