Unfortunately you have not included the directions. Are you supposed to solve for x? or for y?
Suppose the directions say, "Solve for x." Then, clear out the decimal fraction by mult. both sides of the given equation by 10. This will give you the solution, that is, a formula for x in terms of y.

Step-by-step explanation: its goes on forever never stopping
1. b+2=p. 4+2=p. 6=p.
2. p/2=a. 6/2=a. 3=a
3. b-a=x. 4-3=x. 1=x
I'm in HS but this seems like it is the answer. If you need more explanation ask.
