2×+3y=-1
3×+4y=

Answer 1

Respuesta: METODO DE SUSTITUCIÓN

2×+3y=-1

3×+4y=0

$\left \{ {{x=-\frac{1}{2} -\frac{3}{2} y} \atop {3x+4y = 0}} \right.$

$3(-\frac{1}{2} -\frac{3}{2} y) + 4y = 0$

y= -3

$x=-\frac{1}{2} - \frac{3}{2} X (-3)$

x= 4

(x,y) = (4,-3)

ESPERO TE SIRVA, SI ES ASI DAME CORONA

3×+2y=24

×+3y=3

$\left \{ {{3x + 2y = 24} \atop {x=3-3y}} \right.$

3(3-3y)+2y= 24

y= $-\frac{15}{7}$

x = 3 - 3 × $(-\frac{15}{7} )$

x= $\frac{66}{7}$

(x,y) = $(\frac{66}{7}, -\frac{15}{7} )$
