grandmother Alice says my daughter Mary is 26 years younger than me
\n" ); document.write( " and 34 years older than my granddaughter Lisa
\n" ); document.write( " if you add all of our ages together the total is 100
\n" ); document.write( " how old are Alice Mary and Lisa
\n" ); document.write( ":
\n" ); document.write( "Write three equations from the information given here
\n" ); document.write( ":
\n" ); document.write( "A = M + 26
\n" ); document.write( "L = M - 34
\n" ); document.write( "A + M + L = 100
\n" ); document.write( ":
\n" ); document.write( "In the last equation replace A with (M+26); replace L with (M-34), find M
\n" ); document.write( "(M+26) + M + (M-34) = 100
\n" ); document.write( "3M - 8 = 100
\n" ); document.write( "3M = 108
\n" ); document.write( "M = 108/3
\n" ); document.write( "M = 36 yrs is Mary's age
\n" ); document.write( ":
\n" ); document.write( "You should be able to find A and L, ensure they add up to 100 \n" ); document.write( "

\n" );
