Question

Una disculpa pero....
3x - 2y = 13
4x +5y = 2
Lo agradeceria mucho
Es la ultima pregunta que haré :') ​

Answer 1

$3x - 2y = 13 \\ 4x - 5y = 2 \\ \\ x = \frac{13}{3} + \frac{2}{3} y \\ 4x + 5y = 2 \\ \\ 4( \frac{13}{3} + \frac{2}{3} y) + 5y = 2 \\ \\ y = - 2 \\ \\ x = \frac{13}{3} + \frac{2}{3} \times ( - 2) \\ \\ x = 3 \\ \\ (x,y) = (3, - 2) \\ \\ 3 \times 3 - 2 \times ( - 2) = 13 \\ 4 \times 3 + 5 \times ( - 2) = 2 \\ \\ 13 = 13 \\ 2 = 2 \\ \\ = (x,y) = (3, - 2)$
