Solve for x: x +

\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}
