The age of grandmas two grandkids are the same as the two digit of her age. The three of them are 73 years old all together,how old is grandma?
\n" ); document.write( ":
\n" ); document.write( "Two kids, ages x & y
\n" ); document.write( "then
\n" ); document.write( "10x + y = grandma's age
\n" ); document.write( ":
\n" ); document.write( "\"The three of them are 73 years old all together\"
\n" ); document.write( "x + y + (10x + y) = 73
\n" ); document.write( "11x + 2y = 73
\n" ); document.write( "2y = -11x + 73
\n" ); document.write( "y = \"-11%2F2\"x + \"73%2F2\"
\n" ); document.write( "y = -5.5x + 36.5
\n" ); document.write( "The value for x has to be less than 6 avoid a negative number or a decimal
\n" ); document.write( "There is only one single digit positive solution to this equation
\n" ); document.write( "x = 5, then y = 9
\n" ); document.write( ":
\n" ); document.write( "Grandma is 59 yrs old:
\n" ); document.write( ":
\n" ); document.write( "Check: 5 + 9 + 59 = 73 \n" ); document.write( "
\n" );
