5/4x + 1/8 = 9/8 + x
8(5/4x) + 8(1/8) = 8(9/8) + 8(x)
10x + 1 = 9 + 8x
10x + 1 - 8x = 9 + 8x - 8x
2x + 1 = 9
2x + 1 - 1 = 9 - 1
2x = 8
2x / 2 = 8 / 2
x = 8 / 2
x = 4

5/4x + 1/8 = 9/8 + x
5/4x - x = 9/8 - 1/8
1/4 x = 1
x = 4

Just when I answered your other question you deleted it! Lol but I'm still gonna post it so it wasn't a waste of time =]
18(8x+7)=-9(4x-(-2))
Fix the -(- part into a plus:
18(8x+7)=-9(4x+2))
Then distribute:
144x + 126 = -36x - 18
+36x +36x
180x + 126 = -18
-126 -126
180x = -144
x = -144/180
Reduce:
x = -4/5

5/4x=x+9/8 - 1/8
5/4x=x+1
5/4x-x=1
1/4x=1
x=4
