Question

{5x+4y=18}
{6x-3y= 3}​

Answer 1

Respuesta:

$5x + 4y = 18 \\ 5x = 18 - 4y \\ x = \frac{18}{5} - \frac{4}{5} y \\ 5x + 4y = 18 \\ 4x = 18 - 5x \\ y = \frac{9}{2} - \frac{5}{4} x$

$6x - 3y = 3 \\ 6x = 3 + 3y \\ x = \frac{1}{2} + \frac{1}{2} y \\ 6x - 3y = 3 \\ - 3 = 3 - 6x \\ y = - 1 + 2x$
