By the end of summer Timmy doubled the money in his bank account how much money must tell me start with in order to end up at least $60 right a equation and solve

2x = 60; x = 30

x = initial deposit.

the problem states that Timmy doubled the money, therefore the money is already twice as much as the initial deposit. = 2x

2x = 60

2x/2 = 60/2

x = 30

to check:

2x = 60

2 (30) = 60

60 = 60
