Question 19

$u=−i+9j−4k\mathbf{u} = -\mathbf{i} + 9\mathbf{j} - 4\mathbf{k}$ and $v=xi+yj+zk\mathbf{v} = x\mathbf{i} + y\mathbf{j} + z\mathbf{k}$
Given that the resultant displacement of $u\mathbf{u}$ and $v\mathbf{v}$ is $5i−3j+2k5\mathbf{i} - 3\mathbf{j} + 2\mathbf{k}$ , find the values of $x$ , $y\,$ and $z$ .

Find the values of $x$ , $y\,$ and $z$ .
