Sean los vectores \(\mathbf{u}=[2,-1,5,0]\), \(\mathbf{v}=[4,3,1,-1]\) y \(\mathbf{w}=[-6,2,0,3]\). Si \(\mathbf{x}+\mathbf{v}+3\mathbf{w}=2\mathbf{u}\), ¿cuánto suman las coordenadas de \(\mathbf{x}\)?
(%i5) u : [ 2 , 1 , 5 , 0 ] $
v : [ 4 , 3 , 1 , 1 ] $
w : [ 6 , 2 , 0 , 3 ] $
x : 2 · u v 3 · w ;
x [ 1 ] + x [ 2 ] + x [ 3 ] + x [ 4 ] ;

\[\operatorname{ }\left[ 18\operatorname{,}-11\operatorname{,}9\operatorname{,}-8\right] \]

\[\operatorname{ }8\]
