First we need to combine like terms:
-18 + 15x = 12x - 18 + 3x
-18 + 15x = 9x - 18
-18 = 9x - 18 - 15x
-18 = -6x - 18
0 = -6x (the 18's cancel)
0 / -6 = x
0 = x

Answer:Need more information srry
Step-by-step explanation:
You only gave us one number so its kind of hard to answer this it depend on how much marbles you have.
Im srry , I am only a beginner but i hope the so what explanation helped you think about the real question from a lesson or homework you had.
You need to get y alone for both equations. for x-y=7, you subract x from both sides. (giving you -y = 7 - x) then, multiply the whole equation by -1 to make the y positive, which gives you y = x - 7.
here is the system in y intercept form so you can graph it easier:
*y = x - 7
*y = x + 4
