Diketahui a with rightwards arrow on top equals open parentheses table row 3 row cell negative 2 end cell row 5 end table close parentheses space dan space straight b with rightwards arrow on top equals open parentheses table row 1 row 0 row cell negative 4 end cell end table close parentheses dan c with rightwards arrow on top equals 2 a with rightwards arrow on top minus 3 b with rightwards arrow on top, maka

table attributes columnalign right center left columnspacing 0px end attributes row cell c with rightwards arrow on top end cell equals cell 2 a with rightwards arrow on top minus 3 b with rightwards arrow on top end cell row blank equals cell 2 open parentheses table row 3 row cell negative 2 end cell row 5 end table close parentheses minus 3 open parentheses table row 1 row 0 row cell negative 4 end cell end table close parentheses end cell row blank equals cell open parentheses table row 6 row cell negative 4 end cell row 10 end table close parentheses minus open parentheses table row 3 row 0 row cell negative 12 end cell end table close parentheses end cell row blank equals cell open parentheses table row 3 row cell negative 4 end cell row 22 end table close parentheses end cell end table

Sehingga, dengan vektor a with rightwards arrow on top equals open parentheses table row 3 row cell negative 2 end cell row 5 end table close parentheses comma space straight b with rightwards arrow on top equals open parentheses table row 1 row 0 row cell negative 4 end cell end table close parentheses space dan space c with rightwards arrow on top equals open parentheses table row 3 row cell negative 4 end cell row 22 end table close parentheses, dapat ditentukan

a with rightwards arrow on top plus 3 b with rightwards arrow on top minus 2 c with rightwards arrow on top equals open parentheses table row 3 row cell negative 2 end cell row 5 end table close parentheses plus 3 open parentheses table row 1 row 0 row cell negative 4 end cell end table close parentheses minus 2 open parentheses table row 3 row cell negative 4 end cell row 22 end table close parentheses equals open parentheses table row 3 row cell negative 2 end cell row 5 end table close parentheses plus open parentheses table row 3 row 0 row cell negative 12 end cell end table close parentheses minus open parentheses table row 6 row cell negative 8 end cell row 44 end table close parentheses equals open parentheses table row 0 row 6 row cell negative 51 end cell end table close parentheses

Jadi, hasil a with rightwards arrow on top plus 3 b with rightwards arrow on top minus 2 c with rightwards arrow on top equals open parentheses table row 0 row 6 row cell negative 51 end cell end table close parentheses.
