Section Intro

*ex* Solve for (x, y) such that

```
\displaystyle
\begin{cases}
2x + y = 3\\
x - y = -2
\end{cases}
```

Therefore, `(x, y) = (\dfrac{1}{3}, \dfrac{7}{3})`

Introduction of elimination method ex1

*ex* Solve for `(x, y)`

such that

```
\displaystyle
\begin{cases}
2x - 5y = 11\\
5x + 2y = -2
\end{cases}
```

Therefore, `(x, y) = (\dfrac{12}{29}, -\dfrac{59}{29})`

Elimination ex2

*ex* Solve for `(x, y)`

such that

```
\displaystyle
\begin{cases}
ax -3y = 3 \\
2x + by = 12
\end{cases}
```

Therefore, `\dfrac{a(b + 12)}{ab + 6} - 3 = y`
