fredd [130]

Answer:

Since we do not know the balance we should start with, a general answer:

$b_{new} = b_{old} + \sum_{i} d_{i} - \sum_{j} w_{j} \\$

598 - 47,27 = 550,73, assuming b_old was 0$ for your example

Step-by-step explanation:

b stands for balance (old - before any deposits or withdrawals, new after all done)

d for deposits

w for withdrawals

Set up an equation to show (×+2)×5=y

Masteriza [31]

<span>5x+10 = y

Subtract 10 from both sides.

5x = y - 10

Divide both sides by 5.

x = 1/5y - 2

Plugin 1/5y - 2 for the y.
5(1/5y - 2)
1 - 10 + 10 = y

1 = y
