## Introduction of elimination method ex1

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})

## Elimination ex2

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 ex3

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.
