Question

Can someone please help I'm very confused

Answer 1

Row 2: 80

Row 3: -25

Row: 4: -40

Explanation:

This is set up where the old balance +/- the transaction amount will result in the new account balance.

_______________________________________

For example, row 1: 352 - 48 = 304

_______________________________________

For Row 2, we will use x to equal the transaction amount:

432 + x = 512

using simple algebra we subtract 432 from both sides:

432 + x - 432 = 512 - 432

x = 80

For Row 3, new account balance:

75 - 100 = ?

75 - 100 = -25

_______________________________________

For Row 4, we will use x to equal the old account balance:

x + 52 = 12

using simple algebra we subtract 52 from both sides:

x + 52 - 52 = 12 - 52

x = -40

For example, row 5: -10 - 20 = -30
