Solución 5
\[- (x - 4) = - ( 6x - 3 ) - 9\]
\[x = \boxed{-2}\]
\[x = \boxed{-2}\]
Solución 6
\[-1 ( -x - 2 ) = 5 ( -3x + 1 ) - 35\]
\[x = \boxed{-2}\]
\[x = \boxed{-2}\]
Solución 7
\[\frac{2}{5} ( -x - 4 ) = \frac{-5}{4} ( \frac{3}{2}x + 2 ) - \frac{23}{40}\]
\[x = \boxed{-1}\]
\[x = \boxed{-1}\]
Solución 8
\[1 ( \frac{1}{2}x - 1 ) = \frac{3}{5} ( \frac{1}{3}x + 1 ) - \frac{33}{20}\]
\[x = \boxed{\frac{-1}{6}}\]
\[x = \boxed{\frac{-1}{6}}\]
Solución 9
\[-1 ( x + 3 ) = 1 ( x - \frac{5}{2} ) - \frac{5}{2}\]
\[x = \boxed{1}\]
\[x = \boxed{1}\]
