With Year 7 (age 11-12) we have been studying Algebra. When solving equations, I included for a class of high ability students, equations with the unknown on both sides. Having given them one homework where they were exploring various resources for practising solving equations, a sudent asked in a comment on our homework blog how to use Duncan Keith’s excellent linear equation calculator for practising this type of equation:
The slideshow below shows how to use the calculator to solve equations where the unknown is on both sides.
