The Maths Prof: Solve Simultaneous Equations part 1 (by elimination)

Find two unknowns by the elimination method (by adding or subtracting equations together). It's much easier than it sounds! If any of the examples are too easy for you skip to the next one! (Example 2 at 2:58, example 3 at 5:16, example 4 at 9:00 and example 5 at 11:36).

For even harder ones (where you must multiply the equations before using the elimination method) please watch this lesson https://www.youtube.com/watch?v=iQ9rok0vs_U&t=808s
