Question

Please help and no guessing please I need this.

Answer 1

1. n + 8 = 10

2.
`(n)/(12)`= 10

3. 8n - 6 = 34

4. 3(n + 12) = 45

5. No

6. Yes

Explanation:

(only for questions 5 and 6)

5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.

6. If you substitute in b = 8, you get:

`5(8-3)= 25\\5(5) = 25\\25 = 25`

this is true.
