Answer:
Yea that problem is a bit confusing,
2y should be double of what y is, which is 4x+5
Then 2y says 8x+15, when it should be 8x+10.
I feel bad cause I am sure the teacher is wrong on this, he/she had probably made a typo, or you made a typo, but that's ok! We all make typos!
The teacher would be extra rude if they marked you wrong on this, cause the question itself is not written "properly"
Usually ur meant to simplify or something like if u divide the 2 by 2 u get 1y which is 1 and do the same to 8x which is 4x and +15 would be 7.5 but put it in fraction form not decimal. yea u cant get a solution from the 2y
