Well Lets see if I can do this

4X-5
3-7x = 4 if we multiply both sides by the denominator we get

4X-5 = 4(3-7X) multiply this out
4X-5 = 12-28X then bring get rid of the -5 on left
4X=17-28X then get the X's on the other side
28X+4X = 17
32X = 17
X = 17/32

I don't know if this is right because but heck it has been fun and a long time since algebra.

Good luck

Cowgirl: you've got to repost the question. You're missing a left parenthesis in your equation. Is it (4x-5)/(3-7x) = 4 or is it ((4x-5)/3-7x) = 4? Since the outer set of parentheses in ((4x-5)/3-7x) = 4 is unnecssary, you probably meant to write: (4x-5)/(3-7x) = 4; if that is the case then the answer is x = 17/32.

ok, well, if taken exactly as written (4x-5)/3 - 7x = 4 Here's how it works:
add 7x to both sides: 7x + (4x-5)/3 - 7x = 4 + 7x
which gives you: (4x-5)/3 = 4 + 7x
multiply both sides by 3: 3((4x-5)/3) = 3(4 + 7x)
which gives you: 4x-5 = 12+21x
subtract 4x from both sides: -4x+4x-5=12+21x-4x
which gives you: -5=12+17x
subtract 12 from both sides: -12+-5=12+17x-12
which gives you: -17=17x
SO............. x=-1
unless I read it wrong that is!!
Now keep working on your homework BY YOURSELF :)

X = -1

Order of operations makes the problem (4x - 5)/3 -7x =4
Multiply both sides by 3 to get 4x-5 -21x = 12
Simplify to -17x = 17
X = -1

The question if read is erroneous, something is lacking.
It should either be read as :
((4x-5)/3)-7x=4 which will give you a value of x=-1

but if reads
(4x-5)/(3-7x)=4, this should give you x=17/32

(4x - 5) / 3 - 7x = 4
4x - 5 = 4 (3 - 7x)
4x - 5 = 12 - 28x
28x + 4x = 12 + 5
32x = 17
x = 17 /32
