Answer:
[tex]\large\boxed{x<\dfrac{11}{4}\to x\in\left(-\infty,\ \dfrac{11}{4}\right)}[/tex]
Step-by-step explanation:
[tex]3x-\dfrac{1}{4}<8\qquad\text{multiply both sides by 4}\\\\12x-1<32\qquad\text{add 1 to both sides}\\\\12x<33\qquad\text{divide both sides by 12}\\\\x<\dfrac{33}{12}\\\\x<\dfrac{33:3}{12:3}\\\\x<\dfrac{11}{4}[/tex]
