Question

1. In the system below, what is the value of k if x = 4? What is the solution of the system? 6x + 8y = x+y=1
2. In the system below,, what is the value of k if x equals four times the value of yin? what is the solution of the system​

Answer 1

Respuesta:

1.

y=-3

k=0

2.

x=-2

y=-1/2

k=-5/2

Explicación paso a paso:

1.

Si x = 4

x+y=1

4+y=1

 y=1-4

  y=-3

replacing the value of "x " and  "y" in :

6x + 8y =k

6(4)+8(-3)=k

24 -24 =k

   0=k

2.

x=4y

x+y=k

replacing the value of x in:

x+y=k

4y+y=k

5y=k

9x-6k=-3

9(4y)-6(5y)=-3

36y-30y=-3

    6y=-3

      y=-1/2,

replacing the value of y in:

     x=4y=

     x=4(-1/2)=-2,

replacing the value of x and y in:

    k=x+y=

    k=-2+(-1/2)

     k= -5/2
