Let x & y be the two numbers.
\n" ); document.write( "x+y=30 or x=30-y
\n" ); document.write( "2x=y+3
\n" ); document.write( "2(30-y)=y+3
\n" ); document.write( "60-2y=y+3
\n" ); document.write( "-2y-y=3-60
\n" ); document.write( "-3y=-57
\n" ); document.write( "y=-57/-3
\n" ); document.write( "y=19 ans for the larger number.
\n" ); document.write( "x+19=30
\n" ); document.write( "x=30-19
\n" ); document.write( "x=11 ans for the smaller number.
\n" ); document.write( "Proof:
\n" ); document.write( "2*11=19+3
\n" ); document.write( "22=22
\n" ); document.write( "
\n" ); document.write( "
