see to solve the equation which only contains 2 variables noly 2 eqautions are needed.however if 2 equations are complex(difficulty in geeting value of variables)we can use 3rd equation also.let me now consider 2 equation of standard forms
 
 
Ax+By+C=0
ax+by+c=0
 
now on solving for x in 1st eqnt we get”x={-(C+By)}/A
and putting this value in 2nd equation we get:y={aC-Ac}/Ab-Ba
hope u understand
