Question 110850
{{{49 /( 1-1e^3x) = 68}}}…..multiply both sides by {{{( 1-1e^3x)}}}

{{{(49 /(1-1e^3x))*( 1-1e^3x)= 68( 1-1e^3x)}}}

{{{49 = 68( 1-1e^3x)}}}..........divide both sides by {{{68}}}

{{{49/68 = 68/68( 1-1e^3x)}}}.........

{{{0.72= 1-1e^3x}}}..........

{{{ ln 0.72  = 1 -3x}}}..........move {{{-3x}}} to the left and {{{ln.72}}} to the right

{{{3x = 1 - ln .72}}}.......... 

{{{3x = 1 -0.33}}}
{{{3x = 1 -0.33}}}
{{{3x = 0.67}}}
{{{x = 0.67/3}}}
{{{x = 0.2233}}}
