Question

Ken started the day with some money in is pocket. After he took some money out of his bank account, he had $4 more than twice the amount he started with. He then received a birthday present which doubled the amount of money he had with him. Ken now had $100 in his pocket. How much did he start the day with?

I need to know how to do this.

Answer 1

x in the pocket to start

then 4 + 2 x

then 2 (4 + 2 x ) = 100

8 + 4 x = 100

4 x = 92

x = 23
