Simultaneous Equations By Elimination

The video tutorial explains simultaneous equations, which are equations with multiple unknowns that need to be solved together. It introduces three methods for solving them: graphically, by elimination, and by substitution. The focus is on solving linear equations using the elimination method, demonstrated through examples. The tutorial emphasizes the importance of aligning terms and using addition or subtraction to eliminate variables. It concludes with a brief mention of the substitution method for non-linear equations.

How do you determine whether to add or subtract the equations in the elimination method?
