Answer:

x =   \frac{5}{48}

Step-by-step explanation:

\frac{2}{5}  +  \frac{1}{x}  = 10 \\  \frac{1}{x}  = 10 -  \frac{2}{5}  \\  \frac{1}{x}  =  \frac{50 - 2}{5}  \\  \frac{1}{ x }  =  \frac{48}{5}  \\ use  \:  \:  \:  \: cross \:  \:  \:  multiply \\ 5 = 48x \\  \frac{5}{48}  =  \frac{48x}{48}  \\ x =   \frac{5}{48}    \\

This problem can be solved with a series of additions and subtractions.

The starting value is 500 and we first subtract 120 because on Monday they withdrew 120 dollars which leaves us with 380 dollars.

Next, we add 50 because on Wednesday they deposited 50 dollars which results in 430.

And, If I am not mistaken, we are done because when Braxton bought their basketball ticket, they used their debt card and did not withdrew from their checking account.

So, the answer is 430 dollars.
