.
2. Solve this equation:

.
3. Find y:
for

,
for

.
4. The solutions of the system are: (3,-12) and (5,-24).
Answer: Correct choice is A.
Answer:
the first one since it shows all the lines being equal and therefore making the angles equal
72, 96, 84, 12
72 + (7x+24) = 180
7x + 96 = 180
7x = 84
x = 12
