Resolver o sistema 3 variáveis: Para resolver outro sistema, 3x + 2y - z = 4 basta trocar somente os elementos 4x - y + z = 4 das matrizes A e B, adaptados ao x + y + z = 3 novo sistema a ser resolvido.Digite os valores obtidos abai
Resolver o sistema 4 variáveis: Para resolver outro sistema, 3x + 2y - z + w = 10 basta trocar somente os elementos 4x - y + z - w = 6 das matrizes A e B, adaptados ao x + y + z + 3w =12 novo sistema a ser resolvido. 2x +7y -3z + 8w = 28 A matriz inversa de a Inv(A) e a matrix X dos resultados, aparecerão automaticamente.

Resolver o sistema de 5 variáveis: Para resolver outro sistema, 3x1 + 2x2 - x3 + x4 + x5 = 10 basta trocar somente os elementos 5x1 + 7x2 - 8x3 + 5x4 + 3x5 = 17 das matrizes A e B, adaptados ao 7x1 + 13x2 - 4x3 +11 x4 +13x5 = 45 novo sistema a ser resolvido. x1 + 2x2 + x3 - 17x4 - x5 = 57 4x1 + 15x2 + 5x3 - 19x4 +2x5 = 89
