To solve the inequality \( 5a + 18 < -27 \), you can follow these steps:
Step 1: Subtract 18 from both sides.
\( 5a + 18 - 18 < -27 - 18 \)
This simplifies to:
\( 5a < -45 \)
Step 2: Divide both sides by 5.
\( \frac{5a}{5} < \frac{-45}{5} \)
This simplifies to:
\( a < -9 \)
Step 3: Write the final inequality.
The solution is \( a < -9 \).
So, the order of the steps is:
- Step 1: Subtract 18 from both sides.
- Step 2: Divide both sides by 5.
- Step 3: Write the final inequality.
