Last 3: 3/x+1+2/x-1=, x/3=4/x+1, y/4+2y: flip it or leave it

[SglMomNoBrains]

Please help I'm not even sure how to do these problems, I've gone through my ALEKS tutorials and still can't get them. These are my last problems

3/x+1 + 2/x-1 = Rational expressions w/different denominators

x/3=4/x+1 An equation with two solutions

y/4+2y Rational expressions w/different denominators



my problem is that I'm not sure when to flip over or leave as is.
