Magic bag

Each time the prince crossed the bridge, the number of tolars in the magic bag doubled. But then the devil always conjured 300 tolars for him. When this happened for the third time, the prince had twice as much as he had in the beginning. How many tolars did he have in the beginning?

Correct result:

x =  350


2•(2•(2•x-300)-300)-300 = 2•x

6x = 2100

x = 350
