Solve each of the following systems of equations by the method of cross–multiplication.

x – ay = b


ax – by = c

Given: the following systems of equations:


x – ay = b


ax – by = c


To find: The value of x and y


Explanation:


Method of cross multiplication


a1x + b1y + c1 = 0


a2x + b2y + c2 = 0



Here a1= 1 a2 = a


b1= –a b2 = – b


c1= b c2 = c


So, for the given system of equation:









Hence values of x and y are .
