8x - 5y = 31
\n" ); document.write( "x - 4y = 14 multiply by -8 & add.
\n" ); document.write( "-8x+32y=-112
\n" ); document.write( "8x-5y=31
\n" ); document.write( "------------------
\n" ); document.write( "27y=-81
\n" ); document.write( "y=-81/27
\n" ); document.write( "y=-3 ans.
\n" ); document.write( "8x-5*-3=31
\n" ); document.write( "8x+15=31
\n" ); document.write( "8x=31-15
\n" ); document.write( "8x=16
\n" ); document.write( "x=16/8
\n" ); document.write( "x=2 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "2-4*-3=14
\n" ); document.write( "2+12=14
\n" ); document.write( "14=14 \n" ); document.write( "

\n" );
