If A = [(-2,3)(4,5)(1,-6)] and B = B = [(5,2)(-7,3)(6,4)], find a matrix C such that A + B – C = O.

Question

If A = \( \begin{bmatrix} -2 & 3 \\[0.3em] 4& 5 \\[0.3em] 1 &-6 \end{bmatrix}\) and B = \( \begin{bmatrix} 5 & 2 \\[0.3em] -7& 3 \\[0.3em] 6 &4 \end{bmatrix},\) find a matrix C such that A + B – C = O.

A = [(-2,3)(4,5)(1,-6)]

B = [(5,2)(-7,3)(6,4)]

Answer 1

Given A + B – C = 0

Conclusion: C = \( \begin{bmatrix} 3 & 5 \\[0.3em] -3 & 8 \\[0.3em] 7 & -2 \end{bmatrix}\)
