Q13 of 98 Page 310

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

2x - 3y + 1 = 0;


x + 4y + 3 = 0.



To find: - x , y


Given set of lines are : -


2x - 3y + 1 = 0;


x + 4y + 3 = 0


Converting the following equations in matrix form,


AX = B



2R2 – R1



Again converting into equation form we get


2x - 3y = - 1


11 y = - 5


Y =


2x - 3 = - 1


2x = - 1 -


X =


∴
