Find the value for x that makes A parallel to B.
(I will give brainliest!) I appreciate any help

Answer:
x = 5
Step-by-step explanation:
For A to be parallel to B
the alternate exterior angles must be equal
13x - 8 = 9x + 12
Subtract 9x from both sides
4x - 8 = 12
add 8 to both sides
4x = 20
Divide both sides by 4
x = 5
