Help, Missing work!!!

Answer 1

11. x= -3

12. v=8

13. n=19

14. n=171

Explanation:

11. 20+3=23, but since the answer is negative, the 3 has to be negative (different signs = negative)

12. 144/8 = 8, since product is negative, the answer has to be positive (different signs = negative)

13. 133/7= 19, answer must be positive because product is negative (different signs= negative)

14. 9*19=171, so therefore 171/9=19

Answer 2

Explanation:

11) add 20 to both sides, x=-3

12) divide both sides by -8, v=18

13) divide both sides by -7, n=19

14) multiply both sides by 9, n=171
