You can put this solution on YOUR website!
x - 2y = 2 ---1
\n" ); document.write( "x + y = 5 ---2\r
\n" ); document.write( "\n" ); document.write( "multiplying equation 2 by 2\r
\n" ); document.write( "\n" ); document.write( "2x+2y = 10 ---3\r
\n" ); document.write( "\n" ); document.write( "solving equ 1 and 3\r
\n" ); document.write( "\n" ); document.write( "x - 2y = 2
\n" ); document.write( "2x + 2y = 10
\n" ); document.write( "-----------
\n" ); document.write( "3x = 12
\n" ); document.write( "x= 4
\n" ); document.write( "then y = 5-4
\n" ); document.write( "y= 1\r
\n" ); document.write( "\n" ); document.write( "therefore x=4 and y = 1
\n" ); document.write( " \n" ); document.write( "
\n" );
