Question

Se A = $\left[\begin{array}{c}25&12&13\end{array}\right]$ , B = $\left[\begin{array}{c}5&-8&3\end{array}\right]$ e C = $\left[\begin{array}{c}1&10&-1\end{array}\right]$ então x tal que A + B - C - X = 0 é:

Answer 1

X = A + B - C

X = (25 + 5 - 1) =  (29)

     (12 - 8 - 10) = (-6)

     (13 + 3 + 1) = (17)
