The ages of Sean and Bryan now total 49 years.
\n" ); document.write( " Bryan’s age now is twice the age that Sean’s was when Bryan’s age was the same as Sean’s is now.
\n" ); document.write( "How many years old is Bryan?
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"The ages of Sean and Bryan now total 49 years.\"
\n" ); document.write( "s + b = 49
\n" ); document.write( "s = (49-b)
\n" ); document.write( ":
\n" ); document.write( "\"Bryan’s age now is twice the age that Sean’s was when Bryan’s age was the same as Sean’s is now.\"
\n" ); document.write( "b = 2(s - (b - s))
\n" ); document.write( "b = 2(s + s - b)
\n" ); document.write( "b = 2(2s - b)
\n" ); document.write( "b = 4s - 2b
\n" ); document.write( "b + 2b = 4s
\n" ); document.write( "3b = 4s
\n" ); document.write( "Substitute (49-b) for s
\n" ); document.write( "3b = 4(49-b)
\n" ); document.write( "3b = 196 - 4b
\n" ); document.write( "3b + 4b = 196
\n" ); document.write( "7b = 196
\n" ); document.write( "b = \"196%2F7\"
\n" ); document.write( "b = 28 yrs is Bryan's age
\n" ); document.write( "then
\n" ); document.write( "49 - 28 = 21 yrs is Sean's age
\n" ); document.write( ":
\n" ); document.write( "Let see if that works in the statement:
\n" ); document.write( "There is a 7 yr difference in their ages
\n" ); document.write( "\"Bryan’s age now is twice the age that Sean’s was when Bryan’s age was the same as Sean’s is now.\"
\n" ); document.write( "28 = 2(21 - 7)
\n" ); document.write( "28 = 2(14) \n" ); document.write( "
\n" );
