The given equations are,
\n" ); document.write( " 5x+5y=7 . ..(1)
\n" ); document.write( "and 7x-3y=13 ...(2)
\n" ); document.write( "(1)*3 => 15x+15y = 21 ...(3)
\n" ); document.write( "(2)*5 => 35x-15y = 65 ...(4)
\n" ); document.write( "(3)+(4) => 50x = 86
\n" ); document.write( " x = 86/50
\n" ); document.write( " x = 43/25
\n" ); document.write( "(1) => 5*(43/25)+5y = 7
\n" ); document.write( " 43/5+5y = 7
\n" ); document.write( " 5y = 7-43/5
\n" ); document.write( " 5y = (35-43)/5
\n" ); document.write( " y = -8/25
\n" ); document.write( "
\n" ); document.write( "Therefore the solution is,
\n" ); document.write( " x = 43/25 and y = -8/25
\n" ); document.write( " \n" ); document.write( "
\n" );
