wow that is a mouthful take it line by line first
\n" ); document.write( "tens digit=T
\n" ); document.write( "units digit=U
\n" ); document.write( " $\"t=u-3\"$
\n" ); document.write( " $\"n=u%2Bt\"$
\n" ); document.write( " $\"2%2Bn=7u\"$
\n" ); document.write( " $\"2%2Bu%2Bt=7u\"$ substitute and solve
\n" ); document.write( " $\"2%2Bu%2Bu-3=7u\"$
\n" ); document.write( " $\"2u-1=7u\"$
\n" ); document.write( " $\"-1=5u\"$
\n" ); document.write( "but -1/5 cant = u so after doing guess and check there are still no numbers that they could be to fit the above question so this question is IMPOSSIBLE. \n" ); document.write( "
