Step-by-step explanation:

I'm not going to do any of these, i'll just set up the equation for you to find x.

9. 75+x=90

10. x+22=180

11. x=84

12. 82+78+x=180

13. (4x+3)+(x-8)=90

14. (8x+9)+(5x+15)=180 (This was hard to read, check to see if I typed it right.)

15. 2x+4+140=180

16. 4x-13=67+2x

17. 9x+7=115

18. 12x=60

19. 4x=x+21

20. 5x+12+73=180
