Eddie's age is 4 times Marco's.
\n" ); document.write( " In 10 years Eddie will be twice as old as Marco will be.
\n" ); document.write( " How old is each now?
\n" ); document.write( "This has to be solved in the 5-step Method.
\n" ); document.write( ":
\n" ); document.write( "Let e = E's present age
\n" ); document.write( "Let m = M's present age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( "\"Eddie's age is 4 times Marco's.\"
\n" ); document.write( "e = 4m
\n" ); document.write( ":
\n" ); document.write( "\"In 10 years Eddie will be twice as old as Marco will be.\"
\n" ); document.write( "e + 10 = 2(m + 10)
\n" ); document.write( "e + 10 = 2m + 20
\n" ); document.write( "e = 2m + 20 - 10
\n" ); document.write( "e = 2m + 10
\n" ); document.write( "Substitute 4m for e from the 1st equation, find m
\n" ); document.write( "4m = 2m + 10
\n" ); document.write( "4m - 2m = 10
\n" ); document.write( "2m = 10
\n" ); document.write( "m = 5 yrs is M now
\n" ); document.write( "and
\n" ); document.write( "e = 4(5)
\n" ); document.write( "e = 20 yrs is E now
\n" ); document.write( ";
\n" ); document.write( "Check solution in the statement:
\n" ); document.write( "\"In 10 years Eddie will be twice as old as Marco will be.
\n" ); document.write( "20 + 10 = 2(5 + 10)
\n" ); document.write( "30 = 2(15)
\n" ); document.write( ";
\n" ); document.write( "The last step is the sentence about this, I will let you do that\r
