Let we take two equations,
2x+3y-4 = 0
4x+ 8y-14 = 0

To solve the equation,
     x       y       1
3      -4       2      3
8     -14      4      8

 \frac{x}{3(-14)-8(-4)}  \frac{y}{-4(4)-(-14)(2)}  \frac{1}{2(8)-4(3)}

 \frac{x}{-42+32}  \frac{y}{-16+28)}  \frac{1}{16-12}

 \frac{x}{-10}  \frac{y}{12)}  \frac{1}{4}

x = -10/4      and     y = 12/3
x = -5/2        and     y = 4

It is one of the easiest method to solve the linear equations.
