x = 2
given 2 secants from an external point then
Then the product of the external part and the entire secant equals the product of the external part and the entire secant of the other secant.
3 ( 3 + 5 ) = 4 (4 + x )
3 × 8 = 4 ( 4 + x ) ⇒ 24 = 4 ( 4 + x )
divide both sides by 4
6 = 4 + x ⇒ x = 6 - 4 = 2

Step-by-step explanation:
First we set y to the function of x.
y = p(x) = x/2
y = x/2
Now we swap x and y,
x = y/2
Now we solve for y
y = 2x
That's the inverse equation
Answer: y = 2x
