Chapter 4.4, Problem 1E

Linear Combinations In Exercises 1-4, write each vector as a linear combination of the vectors in $S$(if possible).

$S=\left\{\left(2,-1,3\right),\left(5,0,4\right)\right\}$

$\left(\text{a}\right)$ $z=\left(-1,-2,2\right)$ $\left(\text{b}\right)$ $v=\left(8,-\frac{1}{4},\frac{27}{4}\right)$

$\left(\text{c}\right)$ $w=\left(1,-8,12\right)$ $\left(\text{d}\right)$ $u=\left(1,1,-1\right)$
