This video follows on from my video on Simultaneous Equations (Positive) and if you're confident with adding and subtracting negatives (if not watch that video first) then you'll be fine to master this skill that just combines those two skills to give you another tool in your tool belt - Hurrah! We start with examples where we have the same number of one of the unknowns and then move on step by step to the most difficult where you need to multiply both equations first.
