x=4y+5
\n" ); document.write( "x=3y-2
\n" ); document.write( "4y+5=3y-2
\n" ); document.write( "4y-3y=-2-5
\n" ); document.write( "y=-7 ans
\n" ); document.write( "x=4*-7+5
\n" ); document.write( "x=-28+5
\n" ); document.write( "x=-23 ans
\n" ); document.write( "Proof:
\n" ); document.write( "-23=3*-7-2
\n" ); document.write( "-23=-21-2
\n" ); document.write( "-23=-23\r
