Hi!
<h3>To do this, put the values in the equation. </h3>
-2 * 2 + 4 * 5 = -16
<h3>Solve</h3>
-4 + 20 = -16
<u>16 = -16</u>
<h2>(2,5) is not a solution of -2x+4y=-16</h2>
Hope this helps! :)

Answer:
x = 14, y = 12
Step-by-step explanation:
We know that the angles
and
are equal. We also know that they are equal to
. Therefore, when we set up the equality and substitute (14, 12):
![2x+7=180-(12y+1)\\2(14)+7=180-[12(12)+1]\\28+7=180-(144+1)\\35=180-145\\35=35](https://tex.z-dn.net/?f=2x%2B7%3D180-%2812y%2B1%29%5C%5C2%2814%29%2B7%3D180-%5B12%2812%29%2B1%5D%5C%5C28%2B7%3D180-%28144%2B1%29%5C%5C35%3D180-145%5C%5C35%3D35)
Therefore, the solution is x = 14, y = 12.
