Answer 1

what?

Explanation:

Answer 2

Answers are:


1. 6s + 2s - 3s - 6 = 5s - 6

2. 10t - 4t -6 + 5t = 11t - 6

3. 18r + 18r + 9r - 3r = 42r

4. 20 - 4q + 40r - 16 = -4q + 40r + 4

5. 17st - 16s + t = - 16s + 17st + t

6. 101+101x - x = 100x + 101

7. 16a2 - 14a + a2 - 3a = 17a2 - 17a

8. 14t + 14t + t = 29t

9. r + s + rs + s + rs + s = r + 2rs + 3s

10. 54 pt - 3p + 4t - 3pt = -3p + 51pt + 4t

11. 14x2 + 3x2 - x = -x + 17x2

12. 101c - 5c +4c = 100c

13. 12q - 4 + 10q - 4q +9 = 18q + 5

14. 21k - 20k + 3k = 4k

15. 181x + 91x - 23x = 249x

Explanation: If a term contains several variables, it is standard to put the variables in alphabetical order.
Your correct answers may not be in this order.
