I think this is an exponential equation.

I can not figure out how to put the equation into the TI-84 to get the approximate form

3/5 ln(5x-1)+1 =1.4 subtract 1 from

sides and divide

by 3/5

lh(5x-1)=0.6667 Put in logarithm form

e^0.6667=5x-1 add 1 to both sides

e^0.6667=5x Divide by 5

e^0.6667 +1/5 exact form
