First, distribute the 4: $4(7 + 3x) = 28 + 12x$. Set the equation: $28 + 12x = \frac{1}{16}$. Subtract 28: $12x = \frac{1}{16} - 28$. Convert 28 to a fraction: $12x = \frac{1}{16} - \frac{448}{16} = \frac{-447}{16}$. Divide by 12: $x = \frac{-447}{192}$. Simplify: $x = -\frac{149}{64}$, which is approximately -2.328, close to -3.
