Re: Review
Correct a mundo as Fonzie would say.
Have you been shown a simple way to check these. It is not 100% foolproof but it usually finds a wrong one very quickly.
Also I have cleaned up your latex. Use \div when you want ÷.

Re: Review
Just substitute some numbers for x and y. Do a couple of them and the answers should always be the same on both sides. This is not foolproof but will usually find a bad simplification.
I chose x = 10 and y = 5
Check!

Re: Review
Hi;
Did you try checking that on your own as I showed you? Your answer is correct but supposing for the sake of the discussion I said it was wrong?
It is important to have confidence in your own work. I mean confidence because you know it is right.
Do not get me wrong I will check your work as long as you want. But in case you are by yourself...

Re: Review
17-4x=60
17 + -17 + -4x = 60 + -17
-4x = 60 + -17
-4x = 43
Divide by -4
x=-43/4

Yes, that is right. You can surround each of those statements

8+x+-3x=x
8+-2x=x
8+-2x+-1x=x+-1x

8+-3x=x+-1x
8+-3x=0
