Substitution method for linear and non-linear equations

In these tutorials you are shown how to solve a simultaneous equation by the substitution method. You are also shown how it relates to the intersection of two graphs and why there are two sets of solutions.

Example 1

Example in the video

Solve the simultaneous equations:

  1. {x^2} + {y^2} = 5[latex]x + y = 3[/latex]

Example 2

Example in the video

Solve the simultaneous equations:

  1. xy - x = -10[latex]2x + y = 2[/latex]
