3=⅔(n+7)
\n" ); document.write( "3=2(n+7)/3
\n" ); document.write( "2(n+7)=3*3
\n" ); document.write( "2n+14=9
\n" ); document.write( "2n=9-14
\n" ); document.write( "2n=-5
\n" ); document.write( "n=-5/2
\n" ); document.write( "n=-2.5 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "3=2/3(-2.5+7)
\n" ); document.write( "3=2(4.5)/3
\n" ); document.write( "3=9/3
