2. Present the following linear equations in the form of matrices :
(i) 2x + 3y = 13
(ii) 5x + 2y + 3z = 18
5x + 2y = 16
3x + 2y + 3z = 16
(iii) 4x + 3y + 2z + 7 = 0
(iv) x1 + x2 = 2
3x + y - 3z + 5 = 0
x2 + x₂=6
x-5y-7=0
X3 + x4 = 0
B. 2A + 3B and 3A - 2B from the following matrices:
Since, B.B' produces the identity matrix I, the original matrix B is an orthogonal matrix.
