Problem $05\mathrm{.}024-$Source transforming dependent and independent voltage sources to solve a circuit.

With regard to the given circuit, first transform both voltage sources to current sources, reduce the number of elements as much as possible, and determine the voltage $\backslash ($ v$\_\{3\}\backslash ).$ In the given circuit, $\backslash ($ v$\_\{$x$\}=5\backslash$mathrm$\{$~V$\}\backslash ).$

The voltage $\backslash ($ v$\_\{3\}\backslash )$ is

mV $.$
