Let the numbers be X and Y.
\n" ); document.write( "The information you're given is:
\n" ); document.write( "X + Y = 80
\n" ); document.write( "X - Y = 22
\n" ); document.write( "Add them together.
\n" ); document.write( "2X + (Ys cancel each other out) = 102
\n" ); document.write( "Divide each side by 2.
\n" ); document.write( "X = 51
\n" ); document.write( "If X is 51, and X + Y = 80, then Y = 80-51 or 29
\n" ); document.write( ".
\n" ); document.write( "Let's put these back into the original equation to prove.
\n" ); document.write( "X (51) + Y (29) = 80
\n" ); document.write( "51+29 does indeed equal 80.
\n" ); document.write( "Now the other.
\n" ); document.write( "X (51) - Y (29) = 22
\n" ); document.write( "51-29 does indeed equal 22.
\n" ); document.write( ".
\n" ); document.write( "Success!
\n" ); document.write( "
\n" );
