Question 1022318
{{{7e^(3x) + 5 = 40}}}

{{{7e^(3x) = 40-5}}}

{{{7e^(3x) = 35}}}

{{{e^(3x) = 35/7}}}

{{{e^(3x) = 5}}}

{{{log((e^(3x))) = log((5))}}}

{{{(3x)log((e)) = log((5))}}}........since {{{log((e))=1}}}

{{{3x = log((5))}}}

{{{x = log((5))/3}}}

{{{x = 0.69897/3}}}

{{{x = 0.23299}}}

{{{x = 0.233}}}
