You can put this solution on YOUR website!
solve for x: $\"e%5E%28-5x%29%2Ae%5E4=e\"$
\n" ); document.write( "Divide both sides by e^4
\n" ); document.write( " $\"e%5E%28-5x%29=e%2Fe%5E4\"$
\n" ); document.write( "we can write it:
\n" ); document.write( " $\"e%5E%28-5x%29=e%5E%281-4%29\"$
\n" ); document.write( " $\"e%5E%28-5x%29=e%5E-3\"$
\n" ); document.write( "Now we can see that
\n" ); document.write( "-5x = -3
\n" ); document.write( "x = $\"%28-3%29%2F%28-5%29\"$
\n" ); document.write( "x = +.6
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check in the original problem
\n" ); document.write( " $\"e%5E%28-5%2A.6%29%2Ae%5E4=e\"$
\n" ); document.write( " $\"e%5E%28-3%29%2Ae%5E4=e\"$
\n" ); document.write( " $\"e%5E1=e\"$ \n" ); document.write( "
