Q11 of 98 Page 310

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

x + 2y = 1;


3x + y = 4.



To find: - x , y


Given set of lines are : -


x + 2y = 1


3x + y = 4


Converting the following equations in matrix form,


AX = B



R2 – 3R1



Again converting into equation form, we get


x + 2y = 1


- 5y = 1


Y =


x + 2 = 1


x + = 1


x = 1 +


X =


∴ x = , y =
