Answer

The solution is $w\lt \frac{3}{2}$.

Work Step by Step

The given inequality is $\Rightarrow 4(3-w)\gt 3(4w-4)$ Use distributive property. $\Rightarrow 12-4w\gt 12w-12$ Add $4w+12$ to each side. $\Rightarrow 12-4w+4w+12\gt 12w-12+4w+12$ Simplify. $\Rightarrow 24\gt 16w$ Divide each side by $16$. $\Rightarrow \frac{24}{16}\gt \frac{16w}{16}$ Simplify. $\Rightarrow \frac{3}{2}\gt w$ Hence, the solution is $w\lt \frac{3}{2}$.
