Answer:
3/15 hope it helps
Step-by-step explanation:
would be the simplest form
The correct answer is = A + <em> </em>I
Since A is an n × n invertible non singular matrix, exists.
Given equation is + 3A -4I = O where I and O are the n × n identity and zero matrix respectively.
⇒ + 3A -4I = O
⇒ ( + 3A -4I ) = × O
⇒ AA + 3 A - 4I = O
⇒ A + 3I - 4 = O
⇒ A + 3I = 4
⇒ = A + <em> </em>I
Thus the value of can be given by the above equation.
