With the following entries the function is executed only 3 times:

0.0012 STO 0
3.8 STO 2
1 STO I
3,000 ENTER
4,000 SOLVE A
3,166.6667

You can find a description of the algorithm in the paper Personal Calculator Has Key to Solve Any Equation f(x) = 0 by William M. Kahan.

Agreed. My point was using of SOLVE for linear equations is like using a machine gun to kill a mosquito.
