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

Simultaneous equations common mistake 1

Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Solve two simultaneous linear equations in two variables algebraically..

Show the method first, then give the final answer in the required form. Apply this directly to Simultaneous equations.
