-x - 17 < 4x - 2 < 7x - 2
Solution
This inequality is actually two inequalities. We can solve it step by step:
- -x - 17 < 4x - 2
- 4x - 2 < 7x - 2
Let's solve the first inequality:
-x - 17 < 4x - 2
Add x to both sides:
-17 < 5x - 2
Add 2 to both sides:
-15 < 5x
Divide by 5:
-3 < x
So, x > -3
Now, let's solve the second inequality:
4x - 2 < 7x - 2
Subtract 4x from both sides:
-2 < 3x - 2
Add 2 to both sides:
0 < 3x
Divide by 3:
0 < x
So, x > 0
The solution to the original inequality is the intersection of the solutions to these two inequalities. So, the solution is x > 0 and x > -3, which simplifies to x > 0.
