Answer:

9

Step-by-step explanation:

You can take the two equations and set them equal to eachother, basically turning those two into one and getting x+3=3x-15

The way I did it, I subtracted X first leaving me with 3=2x-15

add 15 to both sides, now resulting in 18=2x

divide by two, and you're left with 9.
