SO what i did was made both sides in terms of e and then set the exponents equal to each other and i get 8/11 which i am told is not correct. help please? \n" ); document.write( "

You can put this solution on YOUR website!
e^(2x+1)=9e^(1-x)
\n" ); document.write( "------------------------
\n" ); document.write( "Take the natural log of both sides:
\n" ); document.write( "---
\n" ); document.write( "2x+1 = ln(9) + (1-x)
\n" ); document.write( "3x = ln(9)
\n" ); document.write( "x = [ln(9)]/3
\n" ); document.write( "x = 0.7324..
