Question

sistema da equaçao 3x-2y=2 2x+3y=8

Answer 1

$3x - 2y = 2$
$2x + 3y = 8$
$5x + y = 10$
$y = 10 - 5x$
$2x + 3 (10 - 5x) = 8 \\ 2x + 30 - 15x = 8 \\ - 13x = - 22 \\ x = \frac{ - 22}{ - 13} = \frac{22}{13}$
$3( \frac{22}{13}) - 2y = 2 \\ \frac{66}{13} - 2y = 2 \\ - 2y = 2 - \frac{66}{13}$
$- 2y = \frac{26 - 66}{13} \\ - 2y = \frac{ - 40}{13 }$
$y = \frac{40}{26}$
