For GE 101:

• graph paper: rectilinear ;  semilog ;  log-log
  

• TI 89/92/Voyage Using "Simult" to solve N equations in
  N unknowns simultaneously, where R=row, C=column,
  and there are N rows and N columns in the NxN matrix
  of coefficients:
  Syntax = Simult( [[ R1C1coef, R1C2coef, ... , R1CNcoef ]
                              [ R2C1coef, R2C2coef, ... , R2CNcoef ]
                                           .  .  .
                              [ RNC1coef, RNC2coef, ... , RNCNcoef ]] ,
                             [[ const1 ] [ const2 ] ... [ constN ]] )  see examples
