Question

5x-4y=1 ayudaaaaa porfis

2x-3y=6​

Answer 1

Respuesta:

x= -3

y= -4

Explicación paso a paso:

$\left \{ {{5x-4y=1} \atop {2x-3y=6\​} \right.$

5x(-2/5) - 4y(-2/5)= 1(-2/5)

2x-3y= 6

-2x+8y/5= -2/5

2x-3y= 6

-7y/5= 28/5

-7y= 28

y=$\frac{28}{-7}$

y= -4

hallamos "x"

2x-3y= 6

2x-3(-4)= 6

2x+12= 6

2x=6-12

2x= -6

x= -6/2

x= -3
