Question 109465
 {{{9e^(a-5) = 2e^(5a-2) }}} 

 {{{ln(9e^(a-5)) = ln(2e^(5a-2))}}} 

 {{{ln(9) + ln(e^(a-5)) = ln(2) + ln(e^(5a-2))}}} 

 {{{ln(3^2) + a-5 = ln(2) + 5a-2)}}} 

 {{{2ln(3) + a-5 = ln(2) + 5a-2)}}} 

 {{{2ln(3) -5 - ln(2) + 2 = 5a-a)}}} 

 {{{2ln(3) - ln(2) - 3 = 4a)}}} 

 {{{(2ln(3) - ln(2) - 3)/4 = a)}}}
