Expert verified

Balance in savings account before deposit $= 163.65$ .

Step by step solution

Step-1- Writing formula from given information

Let $x$ be the balance in savings account before deposit.

Balance in savings account after deposit = Balance in savings account before deposit + Amount of money deposited into savings account

Step-2-Solve for value of x

On substituting values, we get

$286.59 = x + 122.94$ .

Subtracting $122.94$ on both sides, we get

$\begin{array}{l} 286.59 - 122.94 = x + 122.94 - 122.94 \\ x = 286.59 - 122.94 \\ x = 163.65 \end{array}$

Step-3-Conclusion

Therefore, the balance in savings account before deposit $= 163.65$ .
