General form of linear eqaution is \\(ax+by+c=0\\)

Substitute the value of x in terms of y from first equation to the second equation.

For cross multiplication method 

\\({x\\over (b_1 c_2-b_2 c_1)}={y\\over(c_1a_2-c_2a_1)}={1\\over(a_1b_2-a_2b_1)}\\)

Use the cross multiplication method.

Put 1/x = a

Use substitution method
