The measure of angle X is 9 degrees more than twice the measure of angle Y. If angle Upper X and angle Y are supplementary angles, find the measure of angle X .

Question

The measure of angle X is 9 degrees more than twice the measure of angle  Y. If angle Upper X and angle Y are supplementary angles, find the measure of angle X .

How would I set this up to solve? This is where I am stuck at?

since they add to 180, and x = 2y+9, 2y+9 + y = 180 Solve for y, and then you can get x.
