Suppose two equations are given..
X+ Y-2 = 0
and
2X+2Y -2 = 0
Then ,
coefficient of X called a1, coefficient of y called b1 and constant term called C.
Therefore,
To find the value of X we apply,
X = b1c2-b2c1/a1b2-a2b1..
To find the value of Y we apply,
Y = c1a2-c2a1/a1b2-a2b1...
And put all the values...
THIS IS CALLED THE CROSS MULTIPLICATION METHOD...
