Holla guys and gals! Recently I hired a private tutor to guide me with some topics in algebra. My problem areas included topics such as simultaneous equations with 4 unknowns and simplifying expressions. Now that instructor turned out to be such a waste, that instead of helping me now I’m even more confused than I used to be. I still can’t solve problems on those topics. And the exam time is nearing. I need someone to help me out. Is there anything in particular that can be done to get some sort of help? I have a fairly large set of questions to help me learn these topics, but the problem is I just can’t solve them, no matter how much effort I put in. Please help!

What specifically are your difficulties with simultaneous equations with 4 unknowns? Can you give some more details . I remember that some time ago I too had to go through a similar period of apprehension . In my instance, my desperate search led me to a tutor in my neighborhood. But he was so tied up that he just did not have the time for me. He was the one who in fact suggested that now-a-days there is yet another solution at hand. He initiated me to these great software programs in math .

Algebrator is used by almost every person in our class. Most of the students in my class work part-time. Our teacher introduced this software to us and we all have been using it since then.

I have tried a number of math programs . I would not name them here, but they were of no use . I hope this one is not like the one’s I’ve used in the past .

I guess you can find all details at this https://mathmusic.org/dividing-rational-expressions.html. As far as I know Algebrator comes at a cost but it has unconditional money back guarantee. That’s how I purchased it. I would advise you to give it a shot. Don’t think you will want to get your money back.
