:
Let b = Becky's age; Let a = Anne's age
:
Write an equation for the statement:
"Amme is twice as old as Becky was when Amme was as old as Becky is now."
a = 2(b - (a-b))
a = 2(b - a + b)
a = 2(2b - a)
a = 4b - 2a
a + 2a = 4b
3a = 4b
:
"If Amme is now 24 years old,"; substitute 24 for a:
3(24) = 4b
72 = 4b
b =
b = 18 is Becky's age now

Check solution in the statement(the difference in their ages is 6):
" Amme is twice as old as Becky was when Amme was as old as Becky is now."
24 = 2(18 - 6)
