$$$$\frac{3}{4}x+\frac{5}{8}=4x$$\\

Subtract $\frac{3}{4}x$ from both sides to get

$$ \frac{5}{8}=3\frac{1}{4}x$$\\

We can write $3\frac{1}{4}$ as the improper fraction: $\frac{13}{4}$ so

$$\frac{5}{8}=\frac{13}{4}x$$\\

Multiply both sides by $\frac{4}{13}$ to get $$\frac{5}{8}\times\frac{4}{13}= x$$ or $$x=\frac{5}{26}$$$$
