Answer 1

hope this helps u......

Answer 2

15. 3n+3 = 12 + 3

3n = 15 - 3

3n = 12

n = 12

3

n = 4

3n-3= 12 -3

3n= 12-3+3

3n= 12

n= 12

3

n= 4

3n×3= 12×3

9n= 36

n = 4

3n = 12

3. 3

n = 4

14. 15 - x = 8

13. 25- 3×4

25- 12

= 13

Sona is 5cm shorter than her sister who is "y" cm long. then height of Sona will be y-5.
