Answer 1

The answer that is the one to pick is the correct one that indeed is the right one a

Answer 2

7. 3r+(-3r)=0

8. 2j + (-9j) =-7j

9. 12 + 4b - 3 + 2c = 4b+2c+9

10. 7y + 8 - 2y + 4 = 5y+12

11. 2a + 3b - 3a + 4c - b = -a+2b+4c

12. i cant see the triangle

13. a 2(x - 5) + (-7) and c 2x - 12

14. a 4(d+6

15. b 25(2 + x + 3y)
