Step 1
\( -3 \mathrm{x}+\mathrm{y}-4 \mathrm{z} = -3(6,-2,-1) + (-4,7,-3) - 4(11,6,8) = (-18,6,3) + (-4,7,-3) - (44,24,32) = (-66,-11,-32) \) Show more…

Solving Systems of Linear Equations
Solving Systems of Three Equations and Applications
Find the values of $x, y$ and $z$ from the following equations: (i) $\left[\begin{array}{ll}4 & 3 \\ x & 5\end{array}\right]=\left[\begin{array}{ll}y & z \\ 1 & 5\end{array}\right]$ (ii) $\left[\begin{array}{cc}x+y & 2 \\ 5+z & x y\end{array}\right]=\left[\begin{array}{cc}6 & 2 \\ 5 & 8\end{array}\right]$ (iii) $\left[\begin{array}{c}x+y+z \\ x+z \\ y+z\end{array}\right]=\left[\begin{array}{l}9 \\ 5 \\ 7\end{array}\right]$
