  1. log[3.7]76.9=3.3191=2x+1, x=1/2(3.3191-1)=1.16 approx.
  2. (x-1)log7=log0.67; x=1+(log0.67/log7)=0.7942.
  3. (x+4)log3=log89; x=log89/log3 - 4=0.0857 approx.
  4. x=log103/log2.7=4.666 approx.
  5. x-4=log[18]413; x=4+log[18]413=6.084 approx.
  6. x+5=log589/log4=4.6011; x=4.6011-5=-0.3989 approx.
