Can someone help me finish this problem I am stuck!
5/4x+1/8x=11/8+x
10/8x+1/8x=11/8+x
11/8x=11/8+x
19/8x=11/8

No. When you had the x on the right, it was correc.
but you have to SUBTRACT x from both sides, you subtracted on the right, but added on the left. 
the problem with your lack of brackets is that we can't decide if you mean
(5/4)x.... or
5/(4x) ....
I am going to take it according to your typing, so I would multiply each term by 8 to give
10x + x = 11 + 8x
3x = 11
x = 11/3
If it is the other option then your line 11/8x=11/8+x
should say
11/(8x) = 11/(8+x)
crossmultiply, then divide by 11 to get
8x = 8+x
x = 8/7 
(5/4)x+(1/8)x=11/8+x
(10/8)x+(1/8)x=11/8+x
(11/8)x=11/8+x
(3/8)x=11/8
Ok now I subtracted from both sides
How do I finish the problem out?
