Use mesh analysis to find out the current through Rx in the circuit below given that:

$R1=2,Rx=12,R2=8$

$V1=13V,Vx=4V,V2=21V$

Mesh current in V$1,$ R$1,$ Rx$,$ Vx $($clockwise$)$

One possible correct answer is: $0\mathrm{.}64285714285714,A$

Mesh current in $Vx,Rx,R2,V2($clockwise$)x$

One possible correct answer is: $-0\mathrm{.}85,A$

Current in Rx $($ darr direction$)$
