Question

For two 3 × 3 matrices $A+B=2B^{T}\ and\ 3A+2B=I_{3}\ where\ B^{T}$ is the transpose of B and $I_{3}$ is 3 × 3 identity matrix. Then:
(a) 5A + 10B = 2$I_{3}$
(b) 10A + 5B = 3$I_{3}$
(c) B + 2A = $I_{3}$
(d) 3A + 6B = 2$I_{3}$

Answer 1

Hello mate ☺

Option A is correct one

Hope it helps u...❤

Answer 2

For two 3 × 3 matrices $A+B=2B^{T}\ and\ 3A+2B=I_{3}\ where\ B^{T}$ is the transpose of B and $I_{3}$ is 3 × 3 identity matrix. Then:

(a) 5A + 10B = 2$I_{3}$✔

(b) 10A + 5B = 3$I_{3}$

(c) B + 2A = $I_{3}$

(d) 3A + 6B = 2$I_{3}$
