Answer:
5
Step-by-step explanation:
The two angles given to us are alternating exterior angle, which means that there measurements would be the same.
Set the two equal to each other.
13x - 23 = 5x + 17
Solve for x. Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Add 23 and subtract 5x from both sides
13x (-5x) - 23 (+23) = 5x (-5x) + 17 (+23)
13x - 5x = 17 + 23
Simplify
8x = 40
Isolate the x. Divide 8 from both sides
(8x)/8 = (40)/8
x = 40/8
x = 5
5 is your answer for x.
