Help with Algebra problem.....?

Question

the problem is 18-2y/4>3/2(y+1/3)=3/2-1/2y the answer is 2>y>or =1/2 but I can't figure out how they got the answer to this problem

Answer 1

Unfortunately, the limits of trying to express a formula using ASCII characters are not helping me understand the exact nature of the original equation. You may wish to try it again, using lots of parentheses to indicate clearly the order of operations.

Answer 2

y +3

Answer 3

The problem should be written in the following way:

(18-2y)/4>3/2(y+1/3)>=3/2-1/2y

if (18-2y)/4=a
3/2(y+1/3)=b
3/2-1/2y=c

then you should find all possible meaning of y (the range of y) for which the equation a>b>=c will have sense.

in order to resolve the problem, it should be sepatated in parts:

1. 3/2(y+1/3)>=3/2-1/2y
3/2y+3/2x1/2>=3/2-1/2y
3/2y+1/2>=3/2-1/2y
3/2y+1/2y>=3/2-1/2
4/2y>=2/2
2y>=1
y>=1/2

This was the first part, so we know the lowest possible meaning of y, now the second part:

2. (18-2y)/4>3/2(y+1/3)
9/2-1/2y>3/2y+1/2
9/2-1/2>3/2y+1/2y
8/2>4/2y
4>2y
2>y

so the range of y is [1/2,2) in other expression 2>y>=1/2

Answer 4

Distribute the 3/2 then find the common denominator so that you can wipe out the fractions. Just follow PEMDAS.

Answer 5

Well, just keep working on it and will come. Let me know once you figured it out.

Answer 6

Neither can I.

In fact....... I can't see how anybody can get much of anything out of that mess that you've put up there.

Answer 7

What is Y arent you suppose to be figuring out what Y is. Seriously e mail me with the answer to that please.
