Answer: 
Explanation:
Follow PEMDAS in reverse to undo what's happening to x.
We first add 1 to both sides, then divide both sides by 5 to fully isolate x.
Refer to the steps below to see what I mean.

The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.
The solution set for x is anything -3 or larger.
If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}

Answer:
4100
Step-by-step explanation:
if on from 0-9 is 1000 on with 0-40 would be 4100
Isolate the x. Subtract 1/3 from both sides
x + 1/3 (-1/3) = 9 (-1/3)
x = 8 3/3 - 1/3
x = 8 2/3
8 2/3 is your answer
hope this helps
