LET Y (UNITS DIGIT) PLUS 6 EQUAL THE TENS DIGIT X
\n" ); document.write( "Y=X-6
\n" ); document.write( "10(X+Y)=10X+Y REPLACE Y WITH (X-6)
\n" ); document.write( "10(X+X-6)=10X+(X-6)
\n" ); document.write( "10(2X-6)=10X+X-6
\n" ); document.write( "20X-60=11X-6
\n" ); document.write( "20X-11X=60-6
\n" ); document.write( "9X=54
\n" ); document.write( "X=54/9
\n" ); document.write( "X=6 WHICH IS THE TENS DIGIT
\n" ); document.write( "Y=6-6=0 FOR THE UNITS DIGIT'
\n" ); document.write( "PROOF
\n" ); document.write( "10(6+0)=10*6+0
\n" ); document.write( "60=60\r
