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:

- [latex]x + y = 3[/latex]

## Example 2

#### Example in the video

Solve the simultaneous equations:

- [latex]2x + y = 2[/latex]
