2s+f=40.75 MULTIPLY BY -2 & ADD
\n" ); document.write( "s+2f=37.25
\n" ); document.write( "-4s-2f=-81.50
\n" ); document.write( "---------------
\n" ); document.write( "-3s=-44.25
\n" ); document.write( "s=-44.25/-3
\n" ); document.write( "s=14.75 ans.
\n" ); document.write( "2*14.75+f=40.75
\n" ); document.write( "29.50+f=40.75
\n" ); document.write( "f=40.75-29.50
\n" ); document.write( "f=11.25 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "14.75+2*11.25=37.25
\n" ); document.write( "29.50+11.25=40.75
\n" ); document.write( "40.75=40.75
