Hint: Ratio are mathematical entities that help in comparison of numbers. In other words a ratio can be defined as a relationship between two numbers that helps in defining the quantity of the first number with the second number.

$\Rightarrow 7x:5x = 8000:TV$
$\Rightarrow 7x - 5x = 8000$
$\Rightarrow x = \dfrac{{8000}}{2} = 4000$
