let the bigger number be a
\n" ); document.write( "smaller number be b
\n" ); document.write( "a-b=10.................1
\n" ); document.write( "..
\n" ); document.write( "2a=b+20
\n" ); document.write( "2a-b=20................2
\n" ); document.write( "multiply equation 1 by -1 and add equation 2 to it
\n" ); document.write( "-1(a-b)+(2a-b)=-10+20
\n" ); document.write( "-a+b+2a-b=10
\n" ); document.write( "a=10
\n" ); document.write( "plug value of a in equation1
\n" ); document.write( "10-b=10
\n" ); document.write( "b=0
\n" ); document.write( "
\n" );
