2. -1 is the solution of 5y + 1 = 4
3. -5 is the solution of 5x + 25 = 0
​

Answer 1

Answer:

1.-

6×3 - 2 = 16

yes

2.-

5 ×-1 +1 = -4

no

3.-

5×-5 +25 = 0

yes

Answer 2

Answer:

1. 6 ( 3) - 2 = 16

18 - 2 = 16

16 = 16

YES

2. 5 ( - 1) + 1 = 4

- 5 + 1 = 4

- 4 = 4

NO

3. 5 ( - 5) + 25 = 0

- 25 + 25 = 0

0 = 0

YES
