Pembahasan

Dengan vektor kolom, Jadi, diperoleh vektor .

Dengan vektor kolom,

table attributes columnalign right center left columnspacing 0px end attributes row cell 3 c with rightwards arrow on top minus e with rightwards arrow on top end cell equals cell 3 open parentheses table row 4 row 2 end table close parentheses minus open parentheses table row 6 row cell negative 4 end cell end table close parentheses end cell row blank equals cell open parentheses table row 12 row 6 end table close parentheses minus open parentheses table row 6 row cell negative 4 end cell end table close parentheses end cell row blank equals cell open parentheses table row 6 row 10 end table close parentheses end cell end table

Jadi, diperoleh vektor table attributes columnalign right center left columnspacing 0px end attributes row blank blank 3 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell c with rightwards arrow on top end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank minus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell e with rightwards arrow on top end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 6 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank i end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank plus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 10 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank j end table.
