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.
