Find matrix X, if [(3,5,-9)(-1,4,-7)] + X = [(6,2,3)(4,8,6)].

Question

Find matrix X, if  \( \begin{bmatrix} 3 & 5 & -9 \\[0.3em] -1 & 4 & -7 \\[0.3em] \end{bmatrix}\) + X = \( \begin{bmatrix} 6 & 2 & 3 \\[0.3em] 4 & 8 & 6 \\[0.3em] \end{bmatrix}.\)

X, [(3,5,-9)(-1,4,-7)]

X =  [(6,2,3)(4,8,6)].

Answer 1

Conclusion : x = \( \begin{bmatrix} 3 &-3& 12 \\[0.3em] 5 & 4 &13\\[0.3em] \end{bmatrix}\)
