$($i$)$ What is the voltage at Vx$?$

$($ii$)$ Write the KVL equation around the base$-$emitter loop. Note: you can write the

voltage difference between the two transistor terminals as VBE for convenience.

$($iii$)$ Given Ie $=($ $+1)$Ib$,$ and your equation in $($ii$),$ solve for Ib$,$ the current through

the Rb resistor.
