Question

p - 10q = 115 / 9-3u = -28 /7u + 11p = -8​

Answer 1

Respuesta:

$\begin{bmatrix}p-10q=11\\ \frac{5}{9}-3u=-2\\ \frac{8}{7}u+11p=-8\end{bmatrix}$

$\begin{bmatrix}p-10q=11\\ \frac{8}{7}\cdot \frac{23}{27}+11p=-8\end{bmatrix}$

$\begin{bmatrix}p-10q=11\\ \frac{184}{189}+11p=-8\end{bmatrix}$

$\begin{bmatrix}-\frac{1696}{2079}-10q=11\end{bmatrix}$
