Answer 1

${( \frac{1}{2} - \frac{3}{4}) }^{3} : {( - \frac{1}{4}) }^{2} - 0.5 = \frac{x}{16} \\ \\ {( - \frac{1}{4}) }^{3} : {( - \frac{1}{4}) }^{2} - \frac{1}{2} = \frac{x}{16} \\ \\ - \frac{1}{4} - \frac{1}{2} = \frac{x}{16} \\ \\ - \frac{3}{4} = \frac{x}{16} \\ \\ - \frac{3 \times 16}{4} = x \\ \\ - 3 \times 16 = 4x \\ \\ - 48 = 4x \\ \\ 4x = - 48 \\ \\ 4x : 4 = - 48 : 4 \\ \\ x = - 48 : 4 = - 12$
