Answer:
x = 20
Explanation:
Let's look at the first parallel lines (the ones with one arrow).
Because both these lines are parallel, we can say that (3x + 2) and (4x - 18) are equal due to the alternate interior angles theorem.
So we have to make both of these expression equal to each other, and then solve:
3x + 2 = 4x - 18
-x = - 20
x = 20 < --- this is your answer
Hope this helps!
