Matemática, perguntado por francysilva321, 1 ano atrás

Me ajudem ????
Dados A= (-1 4 5) (0 2 7) (1 -1 2), B=(3 5 2) (-1 5 3) (4 2 2) e C=(2 7 2) (8 -1 -3) (-1 9 5), calcule a matriz X, tal que: A+B=X+C.

A=  \left[\begin{array}{ccc}-1&4&5\\0&2&7\\1&-1&2\end{array}\right] ~~B=  \left[\begin{array}{ccc}3&5&2\\-1&5&3\\4&2&2\end{array}\right] ~~~C=  \left[\begin{array}{ccc}2&7&2\\8&-1&-3\\-1&9&5\end{array}\right] \\\\\\\\\text{Agora temos que resolver a equacao matricial}\\\\A+B=X+C\\\\\text{Isola o 'X'}\\\\\boxed{X=A+B-C}\\\\\\\text{Entao a matriz X, sera a soma da matriz A com a matriz B e }\\\text{subtraida da matriz C}

 \left[\begin{array}{ccc}-1&4&5\\0&2&7\\1&-1&2\end{array}\right] +\left[\begin{array}{ccc}3&5&2\\-1&5&3\\4&2&2\end{array}\right] - \left[\begin{array}{ccc}2&7&2\\8&-1&-3\\-1&9&5\end{array}\right] \\\\\\X=  \left[\begin{array}{ccc}-1+3-2~~&~~4+5-7~ ~&5+2-2\\~0-1-8~~&~~2+5+1&7+3+3\\1+4+1&-1+2-9&2+2-5\end{array}\right] \\\\\\\\\boxed{X=  \left[\begin{array}{ccc}0&2&5\\-9&8&13\\6&-8&-1\end{array}\right] }~~~~~~~~~~~~~~\longleftarrow\text{Resposta}
