can we combine cases 1&2 and multiply and add throughout as and when necessary to reach the desired format of +xC -1W+0U for instance 100Qs with +2 , -1/2, -1/4 for C,W,U Respectively ? reaching 9,-1,0 or do we solve 2 equations in 3 variables instead?
Try both approaches and see which gives you a correct answer fast 🙂 Both should work, I suspect, first quicker but also more error-prone without practice. Never hurts to have more than one approach…
