Q12 of 98 Page 310

Solve each of the following systems of equations using matrix method.

5x + 7y + 2 = 0;


4x + 6y + 3 = 0.



To find: - x , y


Given set of lines are : -


5x + 7y + 2 = 0;


4x + 6y + 3 = 0.


Converting the following equations in matrix form,


AX = B



5R2 – 4R1



Again converting into equation form, we get


5x + 7y = - 2


2y = - 7


Y =


5x + 7 = - 2


5x = - 2 +


5x =


X =


∴
