Answer:
x = -14
Step-by-step explanation:
Since the angles are opposite angles of straight intersecting lines, they are equal
hence,
9x+184 = 7x+156 (subtract 7x from both sides)
9x - 7x + 184 = 156
2x + 184 = 156 (subtract 184 from both sides)
2x = 156 - 184
2x = -28 (divide both sides by 2)
x = -28 / 2
x = -14
