Ed is 1/6 as old as Laura. In 18 years, Ed's age will be 13 years more than 1/5 of Laura's.
\n" ); document.write( " How old are Ed and Laura now?
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( "\"Ed is 1/6 as old as Laura.\"
\n" ); document.write( "E = \"1%2F6\"L
\n" ); document.write( "or
\n" ); document.write( "L = 6E
\n" ); document.write( ":
\n" ); document.write( "\"In 18 years, Ed's age will be 13 years more than 1/5 of Laura's.\"
\n" ); document.write( "E + 18 = \"1%2F5\"(L+18) + 13
\n" ); document.write( "Multiply by 5 to get rid of these annoying fraction
\n" ); document.write( "5(E+18) = L + 18 + 5(13)
\n" ); document.write( "5E + 90 = L + 18 + 65
\n" ); document.write( "5E = L + 83 - 90
\n" ); document.write( "5E = L - 7
\n" ); document.write( "Replace L with 6E
\n" ); document.write( "5E = 6E - 7
\n" ); document.write( "7 = 6E - 5E
\n" ); document.write( "E = 7 yrs old is Ed
\n" ); document.write( ":
\n" ); document.write( "L = 6(7) = 42 is Laura's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this in the 2nd equation
\n" ); document.write( "7 + 18 = \"1%2F5\"(42 + 18) + 13
