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 =
