Answer:
x = 6°
Explanation:
7x + 5° = 47°, because of alternate exterior angles (We can use this because the lines are parallel). Since we know this, we can solve for x.
Solving this equation:
7x + 5 = 47 and if you subtract by 5 on both sides you would get that 7x = 42. From here, you divide 42 by 7 to get your answer. 42/7 = 6 so x = 6 degrees.
Note: I assumed that the angle 7x + 5 was 7x + 5°
