Ayudenme a resolver esta ecuacion :(( -

io te ayudo UvU ✨

Rpt = x=3 , y=-2

x-y = 5

x + 2y = -1

Resolvemos ↓

$x-y = 5 \\ </strong></p><p><strong>[tex]x-y = 5 \\ x + 2y = -1$

$x = 5 + y \\ x + 2y = - 1$

$5 + y + 2y = - 1$

$y = - 2$

$x = 5 + ( - 2)$

$x = 3$

(x, y) = (3, -2)

-------- verificamos

$3 - ( - 2) = 5 \\ 3 + 2 \times ( - 2) = - 1$

$5 = 5 \\ - 1 = - 1$

Suerte ^-^
