    Yeah, after I find the common denominator then what do I do to the top? Does it change?

    270 works because it's 18*15. Any number that both 18 and 15 go into works. I think 90 is the smallest. I think this is what you're trying to do\[\frac{ 270(x-2) }{ 18 }=\frac{ 270(x-3) }{ 15 }\] and then reduce the whole numbers \[15(x-2)=18(x-3)\] Which is exactly what you got when you cross multiplied
