We begin by discussing what equivalent linear systems are in order to understand why we can multiply, add and subtract equations when we use elimination.  Elimination is the BEST way (imho) to solve linear systems and is a technique that you will use in grade 11 and 12 as well, so learn it well!
SAME SIGN SUBTRACT is a key takeaway!
