Answers:
0. 3x %2b 5 = 20
3x = 15
x = 5
1. 3x %2b 5 - 2 =10
3x %2b3 = 10
2. 30 = 3x %2b 15
15 = 3x
5 = x
x = 5
3. 3x - 5 = 10
3x = 15
4. x/3 = 9
x = 27
5. x/3 %2b 6 = 9
x/3 = 3
x = 9
6. 3x %2b 5 = 3x - 5
7. 3x %2b 5 %2b 2x = 7
3x %2b 2x %2b5 = 7
8. 3x %2b 2x %2b 5 = 7
(3x %2b 2x) %2b 5 = 7
9. 3(x %2b 5) = 30
3x %2b 15 = 30
3x = 15
10. 3x %2b 5 = 3x %2b 5
11. 3x = 18
x = 6
12. 3x %2b 5 = 10
3x = 5
13. 3x %2b 2x -5 = 10
5x - 5 = 10
5x = 15
14. 3(x %2b 5 ) = 3
3x %2b 15 = 3
15. 3x - 5 = 10
3x = 15
x = 5
