The number is between 10 and 100.
\n" ); document.write( "The number is an even number less than 50.
\n" ); document.write( "The sum of the digits in the ones place and the tens place is the double of 5.
\n" ); document.write( "The tens place digit is 2 less than the one place digit.
\n" ); document.write( "What is the number?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. Let be x be the digit of the ones place and let y be the digit of the tens place.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2. Let x+y=2*5=10 since sum of the digits in the ones place and the tens place is the double of 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3. Let y=x-2 since the tens place digit is 2 less than the one place digit\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. We now have a system of linear equations given as \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x+y=10
\n" ); document.write( "-x+y=-2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 5. Add these two equations to get 2y=8 or y=4. Then x=10-4=6. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check...46 satisfies the number between 10 and 100 and the number is an even number less than 50.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 6. ANSWER: The number is 46.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I hope the above steps were helpful.\r
