28 - 9

Step-by-step explanation:

5 + 4 - 3 + 2

5 + 4 can be added together since they have the same radical, they will be treated as if you have 5 apples + 4 apples , which will be 9 apples

Therefore we have

9 - 3 + 2

= X = 2

= X = 3

= X = 5

Returning them back into the expression , we have

9(2) - 3(3) + 2 (5)

⇒ 18 - 9 + 10

= 28 - 9
