(1) 3x -y =2,,,,( 3x -2) =y
\n" ); document.write( ".
\n" ); document.write( "(2) -2x +5y =6,,,,,,,,,,,,,,added x to complete the problem
\n" ); document.write( ".
\n" ); document.write( "subst (1) into (2)
\n" ); document.write( ".
\n" ); document.write( "-2x + 5 (3x -2) = 6
\n" ); document.write( ".
\n" ); document.write( "-2x +15x -10 =6
\n" ); document.write( ".
\n" ); document.write( "13x = 16
\n" ); document.write( ".
\n" ); document.write( "x=16/13
\n" ); document.write( ".
\n" ); document.write( "subst in (1),,,,y = 3 (16/13) -2 = (48 - 26) / 13 = 22/13
\n" ); document.write( ".
\n" ); document.write( "checking
\n" ); document.write( ".
\n" ); document.write( "3(16/13) -(22/13) = (48 - 22) /13 = 26 / 13 = 2,,,,ok
\n" ); document.write( ".
\n" ); document.write( "-2(16/13) + 5 ( 22/13) = ( -32 + 110) / 13 = 78 /13 =6,,,,,ok \n" ); document.write( "

\n" );
