Math Problem Statement
-27 > -4x - 7 and -35 ≥ -4x - 7
Solution
The image contains a system of inequalities:
Solving the first inequality:
- Add 7 to both sides:
- Divide by -4, remembering to reverse the inequality because we are dividing by a negative number:
Solving the second inequality:
- Add 7 to both sides:
- Divide by -4, again reversing the inequality:
Solution:
Now combine both inequalities: This simplifies to:
Thus, the solution to the system of inequalities is .
