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