Explicación paso a paso:
x = 4
y = -3
[tex]2x + 3y = - 1 \\ 3x + 4y = 0 \\ \\ x = \frac{ - 1 - 3y}{2} \\ 3x = - 4y \\ \\ 3( \frac{ - 1 - 3y}{2} ) = - 4y \\ \frac{ - 3 - 9y}{2} = - 4y \\ - 3 - 9y = - 8y \\ - 3 = - 8y + 9y \\ - 3 = y \\ \\ 3x = - 4y \\ 3x = - 4( - 3) \\ 3x = 12 \\ x = \frac{12}{3} \\ x = 4[/tex]
