IN MATH THERE IS NO SUCH THING AS 'CLOSE'.
\n" ); document.write( "CLOSE ONLY COUNTS IN HORSE-SHOES & HAND-GRENADES.
\n" ); document.write( "MATH IS A VERY PRECISE SYSTEM WITH 1 & ONLY 1 CORRECT ANSWER.
\n" ); document.write( "-------------------------------------------------------------------
\n" ); document.write( "Y=4X [Y BEING THE UNITS DIGIT & X BEING THE TENS DIGIT.]
\n" ); document.write( "10X+Y=10Y+X-54 NOW REPLACE Y WITH 4X AND SOLVE FOR X IN THIS EQUATION
\n" ); document.write( "10X+4X=10*4X+X-54
\n" ); document.write( "14X=40X+X-54
\n" ); document.write( "14X=41X-54
\n" ); document.write( "14X-41X=-54
\n" ); document.write( "-27X=-54
\n" ); document.write( "X=-54/-27
\n" ); document.write( "X=2 ANSWER FOR THE TENS DIGIT IN THE ORIGINAL NYMBER.
\n" ); document.write( "Y=4*2=8 FOR THE UNITS DIGIT.
\n" ); document.write( "PROOF
\n" ); document.write( "28=82-54
\n" ); document.write( "28=28\r
