x=3x=3

Explanation:

First, multiply the whole equation by 88

8[5/4x+1/8x=9/8+x]8[54x+18x=98+x]

8(5)/4x+8(1)/8x=8(9)/8+(8)x854x+818x=898+(8)x

cancel(8)color(red)(2)(5)/cancel(4)x+cancel(8)(1)/cancel(8)x=cancel(8)(9)/cancel(8)+(8)x

10x+x=9+8x

11x=9+8x

Now subtract 8x from each side

11x-8x=9+8x-8x

3x=9

Now divide each side by 3

3/3x=9/3

x=3

Final Answer:

x=3
