Question

Encontre o vetor x na resolução da equação 2(u-v)+2x=u-3x+v omde u=(2,-2,3) e v=(4,1,-2)

Answer 1

Oi 

u = (2, -2, 3) e v = (4, 1, -2)

2*(u - v) + 2*(x1, x2, x3) + v 

2*(-2, -3, 5) + 2*(x1,x2,x3) + (4, 1, -2) 

-2*(x1, x2, x3) = (-4 , -6, 10) + (4, 1, -2)

-2*(x1, x2, x3) = (0, -5, 8)
2*(x1, x2, x3) = (0, 5, -8) 

x = (0, 5/2, -8/2)
