1\x+5 = 2\2x+1 and 3\2y+2y\y-4= -11\2

I'm struggling with Least Common Denominator mostly.

With stuff like this, you usually wont have luck with least common denominators.
In the first equation, you are actually better off cross multiplying to get 2x+1 = 2x+10, which is inconsistant.
In the second equation, 2y(y-4) is your common denominator, soyou will have

3(y-4) + (2y)^2 = (-11)*(y(y-4))
You can work out the math to solve this.

you have to be more specific is it 1/(x+5) or (1/X)+5 put parantheses in your equations in all of them.
