Question

Sejam as matrizes do tipo 1x4, A = [x/3 5 3z-1 4] e B = [2 y-6 -7 4]. Sabendo que A = B, determine os valores de x, y e z

Answer 1

Resolução:$\left[\begin{array}{cccc} \frac{x}{3} &5&3z-1&4\\\end{array}\right] = \left[\begin{array}{cccc}2&y-6&-7&4\\\end{array}\right]$

$\frac{x}{3}=2 ----\ \textgreater \ x = 6$

$5 = y-6 -------\ \textgreater \ y = 5 + 6 -----\ \textgreater \ y = 11$

$3z-1 = -7 ----\ \textgreater \ z = (-7 +1)/3 -----\ \textgreater \ z = -2$

$4 = 4$
