If x and y are positive integers and 3x+5y = 18 what is value of x?

OpenStudy (campbell_st):

just try some values like y = 1 or 2 or 3 or 4 and substitute them see what you get for x.. just a thought

OpenStudy (anonymous):

you can plug any positive number in for y and it will give you a value of x. If you were trying to just get x on it's own I believe you would just solve for x which would get x=18-5y/3.... sorry if It's confusing
