To solve the inequality \( 5a + 18 < -27 \), here is the correct order of steps:
Step 1: Subtract 18 from both sides of the inequality.
Step 2: Divide both sides by 5.
Step 3: Write the solution in interval notation or another appropriate form.
Now, to solve the inequality:
-
Step 1: Subtract 18 from both sides: \[ 5a + 18 - 18 < -27 - 18 \] This simplifies to: \[ 5a < -45 \]
-
Step 2: Divide both sides by 5: \[ a < -9 \]
So, the solution set is: \[ (-\infty, -9) \]
In summary, the steps to input would be:
- Step 1: Subtract 18 from both sides.
- Step 2: Divide both sides by 5.
- Step 3: Write the solution.
The solution set is \( a < -9 \) or in interval notation \( (-\infty, -9) \).
