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 =
∴
