Answer:

Value of x=0

<u>Step-by-step explanation:</u>

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 ify=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)

mezya [45]

Answer:

The price of the tv before tax is 410

Step-by-step explanation:

Let x = price of tv before tax

tax = x*  9%

tax = .09x

The total cost is price of tv before tax plus tax

total cost = x + .09x

total cost = 1.09x

446.90 = 1.09x

Divide each side by 1.09

446.90/1.09 = 1.09x/1.09

410 = x

The price of the tv before tax is 410
