This i all the instruction there is me, i'm very confused.

So first you would have to work with the y's since they are consecutive angles.Consecutive angles would add up to 180 so the problem would be
5(y+11)^0+4y-10=180 then simplify
10+4y-10=180
4y=180
y=45
Then plug in the y for the top problem and the add the answer to the x problem and set them to 180 because they are also a linear pair and you should get your answer
I got x=34

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
