Steps ;
1) add the five to the 15 (since it’s a negative to the other side of the equal sign)
2) dived 2 from 2y and 20
3) y should equal 10

Answer:

y = 10


Step-by-step explanation:

Unsure of why you've included "plus."  -5 + 2y = 15 is an equation in one variable.  Adding 5 to both sides results in 2y = 20, so that y = 10.  That's it.
