Simultaneous Linear EquationsSimultaneous Linear EquationsConsider two linear equations in two variables, x and y, such as 2x  3y = 4 3x + y
= 1 Intersection Point of a Line with a Horizontal or Vertical LineWe first consider the special cases of solving a pair of simultaneous linear equations when one of the two lines is either horizontal (ay = b) or vertical (cx = d); the solution in these cases is easily found by substitution. Example 1A.Case one: One line is horizontal (ay = b): Exercise 1A.Now try solving a few on your own: Example 1B.Case two: One line is vertical (cx = d). The method is exactly the same as for a vertical line. Exercise 1B.Practice this method with a few exercises: Simultaneous Linear Equations Index  The Elimination Method >>
