\( \begin{array}{ll}\text { 5. } \frac{n}{-14}=2 & \text { 6. } 49=-7 x \\ \text { 9. } 6=\frac{c}{7} & \text { 10. } 3 a=-45 \\ \text { 13. }-48=-12 c & \text { 14. } \frac{c}{-8}=9\end{array} \)

**5. \( \frac{n}{-14} = 2 \)** Multiply both sides by \(-14\): \[ n = 2 \times (-14) = -28 \] --- **6. \( 49 = -7x \)** Divide both sides by \(-7\): \[ x = \frac{49}{-7} = -7 \] --- **9. \( 6 = \frac{c}{7} \)** Multiply both sides by \(7\): \[ c = 6 \times 7 = 42 \] --- **10. \( 3a = -45 \)** Divide both sides by \(3\): \[ a = \frac{-45}{3} = -15 \] --- **13. \( -48 = -12c \)** Divide both sides by \(-12\): \[ c = \frac{-48}{-12} = 4 \] --- **14. \( \frac{c}{-8} = 9 \)** Multiply both sides by \(-8\): \[ c = 9 \times (-8) = -72 \]
