Resposta :
3 A= [-12 0]
[3 -18]
2C = [6 20]
[ -12 0]
2C+ B = [9 30]
[-18 0]
3 A- X =2C+ B
Resolvendo, temos:
[-12 0] + X = [9 30] X= [ 9 – (-12) 30 – 0]
[3 -18] [-18 0] [ -18 -3 0 – (-18)]
X= [21 30]
[-21 -18]
dadas as matriz A=(-4 0) B=(5 8) C=(3 10)
(1 -6) (1 -2) (-6 0) a matriz X de ordem 2 a equação 3A-X=2C+B
3 A= [-12 0]
[3 -18]
2C = [6 20]
[ -12 0]
2C+ B = [9 30]
[-18 0]
3 A- X =2C+ B
Resolvendo, temos:
[-12 0] + X = [9 30] X= [ 9 – (-12) 30 – 0]
[3 -18] [-18 0] [ -18 -3 0 – (-18)]
X= [21 30]
