This is a useful worksheet with questions on solving a range of linear equations, the solutions are given too which is helpful. You could give this to students as a homework task or as a quick assessment in class, it could be self or peer marked using the solutions. Phildb has shared a lot of similar A-level resources which you could put together to make a question booklet for students. Questions like this which cover GCSE material could be given to students before they start the course to get them up to speed. Thank you for sharing.
