The main challenge is writing the problem in math instead of English. Let the angle be x. Then it's supplement is 180-x. Half its supplement is (180-x)/2. The angle is 9 more than it supplement, so: \[x=\frac{180-x}{2}+9\] Do you see how to solve the equation now?
OpenStudy (anonymous):

OpenStudy (anonymous):
Yeah, exactly. Multiply each side by 2.
