Answer:
Put your equation into this!
Step-by-step explanation:

It will graph it for you!
You are very welcome!!
4x = (130 - 2x) so x = 65/3
(3y + 40) + (130 -2x) = 180 because the angles are supplementary
plug in x
3y + 40 + 130 - 2(65/3) = 180
so 3y = 95/3
therefore y = 95/6
Wouldnt it be the out side numbers ?at both ends?
