Q4 of 92 Page 69

Let us solve the following linear simultaneous equations in two variables by the method of elimination:

ax + by = c


a2 x + b2y = c2

In this case, we will eliminate y from both the equations

ax + by = c (i)


(ii)


Multiplying equation (i) by ‘b’ we get,




Putting the value of x in equation (i) we get,



Hence the solution of the linear equation is and
