Lucas was 50 years old when his granddaughter was born.
\n" ); document.write( " Now he is two years more than four times his granddaughter's age.
\n" ); document.write( " How old is his granddaughter now?
\n" ); document.write( ":
\n" ); document.write( "Let L = Lucas's present age
\n" ); document.write( "Let d = daughter's present age
\n" ); document.write( "From the given information we know:
\n" ); document.write( "L = d+50
\n" ); document.write( ":
\n" ); document.write( "\"Now he is two years more than four times his granddaughter's age.\"
\n" ); document.write( "L = 4d + 2
\n" ); document.write( "we know L = (d+50), replace L in the above equation
\n" ); document.write( "d + 50 = 4d + 2
\n" ); document.write( "50 - 2 = 4d - d
\n" ); document.write( "48 = 3d
\n" ); document.write( "d = 48/3
\n" ); document.write( "d = 16 yrs is granddaughter's present age\r
