Question

dadas as matrizes A=2,0,1,-1 B=3,-1,0,1 C=0,2,-1,0.determine a matriz X que verifica a equqcao 2×A+B=X+2×C

Answer 1

Ola Clara

2A = (4, 0, 2, -2)

B = (3, -1, 0, 1)

2A + B = (7, -1, 2, -1)

2C = (0, 4, -2, 0)

(7, -1, 2, -1) = X + (0, 4, -2, 0)

X = (7, -1, 2, -1) - (0, 4, -2, 0)

X = (7, -5, 4, -1)
