Question

$3X+Y= -7X+3Y=3PLISS RAPIDOOOOOO$

Answer 1

Respuesta:

x= 3/8

y= 15/8

Explicación paso a paso:

$3x + y = 3 \\ - 7x + 3y = 3$

$y = 3 - 3x$

$- 7x + 3 \times (3 - 3x) = 3$

$- 7x + 9 - 9x = 3$

$- 16x = - 6$

$x = \frac{6}{16} = \frac{3}{8}$

$y = 3 - 3 \frac{3}{8}$

$y = 3 - \frac{9}{8}$

$y = \frac{24 - 9}{8}$

$y = \frac{15}{8}$
