Question

Determinar o vetor v, sabendo que: (3,7,1) + 2v = (6,10,4) - v

Answer 1

(3,7,1) + 2v = (6,10,4) - v 

(3,7,1) + 3v = (6,10,4) 

3v = (6-3,10-7,4-1) 

3v = (3,3,3) 

v = (1,1,1)

Answer 2

(3,7,1) + 2v = (6,10,4) - v

 2v+ v = (6,10,4) - (3,7,1)  

    3v = ( 3, 3, 3 )

       v = ( 1, 1, 1)
