5/4x+1/8x=11/8+x

10/8x+1/8x=11/8+x

11/8x=11/8+x

19/8x=11/8

**bobpursley**, Wednesday, January 7, 2009 at 11:19amNo. 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.

**Reiny**, Wednesday, January 7, 2009 at 11:21amthe 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)

cross-multiply, then divide by 11 to get

8x = 8+x

x = 8/7

**deedra**, Wednesday, January 7, 2009 at 11:32am(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?
