Question

5X - 2Y = 3
7X - 4Y = 3

Answer 1

Respuesta:

$\begin{bmatrix}5x-2y=3\\ 7x-4y=3\end{bmatrix}\\\\\\\begin{bmatrix}7\cdot \frac{3+2y}{5}-4y=3\end{bmatrix}\\\\\\\begin{bmatrix}\frac{21-6y}{5}=3\end{bmatrix}\\\\\\x=\frac{3+2\cdot \:1}{5}\\\\\\x=1\\\\\\\mathrm{Las\:soluciones\:para\:el\:sistema\:de\:ecuaciones\:son:}$
