\n" ); document.write( "
ln (5 - x) + ln 3 = ln 6
\n" ); document.write( "ln 3(5 - x) = ln 6 ---- Applying the following: \"ln+%28a%29+%2B+ln+%28b%29+=+ln+%28a+%2A+b%29\"
\n" ); document.write( "3(5 - x) = 6 ---------- Applying the following: \"ln+%28c%29+=+ln+%286%29\" becomes \"c+=+6\"
\n" ); document.write( "15 - 3x = 6
\n" ); document.write( "- 3x = 6 - 15
\n" ); document.write( "- 3x = - 9
\n" ); document.write( "x = \"%28-+9%29%2F%28-+3%29\", or \"highlight_green%28x+=+3%29\"
\n" ); document.write( "Be reminded that you're not finished yet. The value(s) you get for the variable should make the ORIGINAL equation
\n" ); document.write( "TRUE, so 3 should be substituted, for x, in the original equation: ln (5 - x) + ln 3 = ln 6, to determine if the
\n" ); document.write( "value for x is correct. This is a MUST since there are times when a value may prove to be an EXTRANEOUS solution.
