4x+3y=4 .............1
\n" ); document.write( "4x-y=0 .............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "4x+3y=4
\n" ); document.write( "12x-3y =0
\n" ); document.write( "
\n" ); document.write( "Add the two equations
\n" ); document.write( "
