8 Halla la solución de estas ecuaciones. a) \( \frac{2-x}{4}-\frac{5-x}{3}=\frac{x+3}{6} \) b) \( \frac{3 x-5}{2}=\frac{5+3 x}{4}-\frac{x}{8} \) c) \( \frac{2 x+5}{6}=\frac{4-x}{9}-\frac{2 x-5}{3} \)

Solve the system if possible by using Cramer's rule. If Cramer's rule does not apply, solve the system by using another meth Write all numbers as integers or simplified fractions. \[ \begin{array}{l}7 x+7 y=-19 \\ \\ -9 x-5 y=4 \\ \text { Part: } 0 / 2 \\ \text { Part } 1 \text { of } 2 \\ \text { Evaluate the determinants } D_{1} D_{x} \text {, and } D_{y} \\ D=\square\end{array} \] \( \square \)
