To solve the inequality \(5a + 18 < -27\), we can break down the steps as follows:
Step 1
Subtract 18 from both sides: \[ 5a + 18 - 18 < -27 - 18 \] Resulting in: \[ 5a < -45 \]
Step 2
Divide both sides by 5: \[ \frac{5a}{5} < \frac{-45}{5} \] Resulting in: \[ a < -9 \]
Step 3
Write the solution set: The solution set can be expressed as: \[ (-\infty, -9) \]
Summary
Here is the ordered list of steps:
- Step 1: Subtract 18 from both sides.
- Step 2: Divide both sides by 5.
- Step 3: Write the solution set.
Solution Set
