6. $2c + 2 = 16 \\ 2c = 16 - 2 \\ 2c = 14 \\ c = 14 \div 2 \\ c = 7$
8. $3c + 3 = 15 \\ 3c = 15 - 3 \\ 3c = 12\\ c = 12 \div 3 \\ c = 4$.
10. $3c + 6 = 12 \\ 3c = 12 - 6 \\ 3c = 6 \\ c = 6 \div 3 \\ c = 2$
12. $3x + 9 = 15 \\ 3x = 15 - 9 \\ 3x = 6 \\ x = 6 \div 3 \\ x = 2$
14. $3x + 8 = 29 \\ 3x = 29 - 8 \\ 3x = 21 \\ x = 21 \div 3 \\ x = 7$
16. $2c + 1 = 19 \\ 2c = 19 - 1 \\ 2c = 18 \\ c = 18 \div 2 \\ c = 9$
18. $3x + 6 = 15 \\ 3x = 15 - 6 \\ 3x = 9 \\ x= 9 \div 3 \\ x = 3$
20. $2u + 8 = 10 \\ 2u = 10 - 8 \\ 2u = 2 \\ u = 2 \div 2 \\ u = 1$
22. $3x + 7 = 13 \\ 3x = 13 - 7 \\ 3x = 6 \\ x = 6 \div 3 \\ x = 2$
24. $3c + 2 = 29 \\ 3c = 29 - 2 \\ 3c = 27 \\ c = 27 \div 3 \\ c = 9$
