Question

Solve this system using substitution:

Answer 1

Answer:

Value of x=0

Step-by-step explanation:

Given:

     if $y=5$

To find:

   $16 x-4 y=-20$

Solve this system using substitution method and find the value of x

Solution:

The given equation:$16 x-4 y=-20$

And if$y=5$  

Substitute the value of y=5 in the above equation, we get

    $16 x-4(5)=-20$

    $16 x-20=-20$

    $16 x=-20+20$

    $16 x=0$

    $x=0$

Result:

Value of x=0 and (x, y)=(0,5)

Answer 2

Answer:

16x- 20y=20

Step-by-step explanation:

20y-20y =0

so answer is 16x
