Question

the value of x.

Explanation:

Step1: Assume parallel lines

If the two horizontal lines are parallel, then the corresponding angles are equal. So we set up the equation $3x - 9=4x - 25$.

Step2: Rearrange the equation

Move the $x$ - terms to one side: $4x-3x=25 - 9$.

Step3: Calculate the value of $x$

$x = 16$.

Answer:

$x = 16$
