Write and solve a system of equations to find the values of x and y.

2y + 5x = 90  

       

2y + 5x + y + 7x = 180 or       3y + 12x = 180

 

Can you solve the equations?

Would it not be 360 because it's a circle? If it is 180, I believe the answer would be x =5 and y = 40? 

 

If it's 360, it would be x = 15 and y = 60. 

 

Any ideas which one it is?
