C) (1)/(12)x-75% x=-1(2)/(3)

1. Convert percentages and mixed numbers to fractions: $\frac{1}{12}x - \frac{3}{4}x = -\frac{5}{3}$<br /><br />2. Find a common denominator for the x terms: $\frac{1}{12}x - \frac{9}{12}x = -\frac{5}{3}$<br /><br />3. Combine the x terms: $-\frac{8}{12}x = -\frac{5}{3}$<br /><br />4. Simplify the fraction: $-\frac{2}{3}x = -\frac{5}{3}$<br /><br />5. Multiply both sides by $-\frac{3}{2}$: $x = \frac{5}{3} \times \frac{3}{2}$<br /><br />6. Simplify: $x = \frac{5}{2}$<br />
