3x - 2y = 11
\n" ); document.write( "x - y/2 = 4 multiply by 3 & subtract.
\n" ); document.write( "3x-2y=11
\n" ); document.write( "-(3x-3y/2=12)
\n" ); document.write( "----------------
\n" ); document.write( "-2y+3y/2=-1
\n" ); document.write( "(-2y*2+3y)/2=-1
\n" ); document.write( "(-4y+3y)/2=-1
\n" ); document.write( "-y/2=-1
\n" ); document.write( "-y=-2
\n" ); document.write( "y=2 ans.
\n" ); document.write( "3x-2*2=11
\n" ); document.write( "3x-4=11
\n" ); document.write( "3x=11+4
\n" ); document.write( "3x=15
\n" ); document.write( "x=15/3
\n" ); document.write( "x=5
\n" ); document.write( "Proof:
\n" ); document.write( "5-2/2=4
\n" ); document.write( "5-1=4
\n" ); document.write( "4=4\r
