a number of 3 digits is such hat the tens digit exceeds the unit digit by 2.
\n" ); document.write( " If this number exceeds the number formed by reversing the digits by 297
\n" ); document.write( "and if the sum of its digits is 14, find the number.
\n" ); document.write( ":
\n" ); document.write( "Let a = the 100's digit
\n" ); document.write( "Let b = the 10's digit
\n" ); document.write( "Let c = the units
\n" ); document.write( "then
\n" ); document.write( "100a + 10b + c = \"the 3digit number
\n" ); document.write( "and
\n" ); document.write( "100c + 10b + a = the number reversed
\n" ); document.write( ":
\n" ); document.write( "\" the tens digit exceeds the unit digit by 2.\"
\n" ); document.write( "b = c+2
\n" ); document.write( ":
\n" ); document.write( "\" If this number exceeds the number formed, by reversing the digits by 297\"
\n" ); document.write( "100a + 10b + c = 100c + 10b + a + 297
\n" ); document.write( "Combine like terms
\n" ); document.write( "100a - a + 10b - 10b = 100c - c + 297
\n" ); document.write( "99a = 99c + 297
\n" ); document.write( "Simplify, divide by 99
\n" ); document.write( "a = c + 3
\n" ); document.write( ":
\n" ); document.write( "\"the sum of its digits is 14,\"
\n" ); document.write( "a + b + c = 14
\n" ); document.write( "replace a with (c+3), replace b with (c+2)
\n" ); document.write( "c + 3 + c + 2 + c = 14
\n" ); document.write( "3c + 5 = 14
\n" ); document.write( "3c = 14 - 5
\n" ); document.write( "c = 9/3
\n" ); document.write( "c = 3
\n" ); document.write( ":
\n" ); document.write( "I'll let you find a and b
\n" ); document.write( "check the number you come up with in each statement
\n" ); document.write( "
