You can put this solution on YOUR website! Each angle must measure 60 degrees. Therefore, 2y = 60 --> y = 30.
Now use the first angle 3x + y, replace y with 30. It is equal to 60, so x is 10.
The remaining angle, 2x+40, is already equal to 60 since if we replace x with 10, we get 60.
So, x = 10, y = 30.
