6x-2y=10
\n" ); document.write( "-(x-2y=-5) subtract.
\n" ); document.write( "------------------
\n" ); document.write( "5x=15
\n" ); document.write( "x=15/5
\n" ); document.write( "x=3 ans.
\n" ); document.write( "3-2y=-5
\n" ); document.write( "-2y=-5-3
\n" ); document.write( "-2y=-8
\n" ); document.write( "y=-8/-2
\n" ); document.write( "y=4 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "6*3-2*4=10
