Question $3$: BJT DC Analysis

Compute current $I_1$ in the circuit shown below.

Assume:

$V_{BE}(on)=0\mathrm{.}7V,V_{CE}($ sat $)=0\mathrm{.}2V,=100$

$V_{CC1}=10V,V_{CC2}=2\mathrm{.}3V,R_C=0\mathrm{.}39k,R_E=0\mathrm{.}1k,R_B=1\mathrm{.}01k.$

$I_1=$ number $($rtol $=0\mathrm{.}01,$ atol $=1e-05)$
