2x+3y=13 .........(1)
\n" ); document.write( "3x+5y=10 ..........(2)\r
\n" ); document.write( "\n" ); document.write( "Multiply (1) by 3 and (2) by 2
\n" ); document.write( "6x+9y=39.........(3)
\n" ); document.write( "6x+10y=20........(4)
\n" ); document.write( "Subtract (4) from (3)\r
\n" ); document.write( "\n" ); document.write( "6x+9y=39
\n" ); document.write( "-6x-10y=-20
\n" ); document.write( "------------------
\n" ); document.write( "-y=19
\n" ); document.write( "Multiply above equation by (-1)
\n" ); document.write( "(-1)(-y)=(-1)(19)
\n" ); document.write( "y=-19
\n" ); document.write( "Put the value of y in (1)
\n" ); document.write( "2x+3y=13 .........(1)
\n" ); document.write( "2x+3(-19)=13
\n" ); document.write( "2x-57=13
