I would help but I'm not sure what you are asking for us to do
Answer:
180
Step-by-step explanation:
im sure that is 180 so if you did not believe me solve that and be ready for your task and your brain
Y = -7x + 2
y = 9x - 14
-7x + 2 = 9x - 14
14 + 2 = 9x + 7x
16 = 16x
1 = x
y = -7x + 2
y = -7(1) + 2
y = -7 + 2
y = -5
solution is : (1,-5) <==
