Question 159201: I need help on how to solve these problems.

1. 21=7x less than or equal to 7(3+x)

2. 9(w+2) < 9w +17

3. 13(r+1) < 13r-6

4. 2a-16 greater than or equal to 2a-17

5. 3t-12 > 3t+2
6. 2-3g+7 greater than or equal to 3(2-g)

You can put this solution on YOUR website!
1. 21=7x less than or equal to 7(3+x)
Here you wrote = but is wrong
2. 9(w+2) < 9w +17
9w%2B18%3C9w%2B17 then 18%3C17 (no solution)
3. 13(r+1) < 13r-6
13r%2B13%3C13r-6 then 13%3C-6 (no solution)
4. 2a-16 greater than or equal to 2a-17
2a-16%3E=2a-17 then -16%3E=-17 ( solution is all real numbers)
5. 3t-12 > 3t+2 then -12%3E2 (no solution)
6. 2-3g+7 greater than or equal to 3(2-g)
then 9-3g%3E=6-3g then 9%3E=6 then ( solution is all real numbers)
