Could you please help me answer this question?

The first angle of a triangle is eight degrees more than two times 
the third angle. The second angle is two degrees less than three 
times the third angle. Find all three angles.

Hello -

Here's a hint: you'll have to use the fact that the three angles of 
this triangle add up to 180 degrees.  So use some algebra: let x be 
the first angle, y be the second angle, and z be the third angle.  
Then try to find 3 equations that relate x, y, and z.  Good luck, and 
write back if you're still confused!
