Final answer:
The solution to the inequality 10x + 18 < -2 is x < -2.
Step-by-step explanation:
To solve the inequality 10x + 18 < -2, we'll start by subtracting 18 from both sides to isolate the variable:
10x + 18 - 18 < -2 - 18
10x < -20
Next, divide both sides by 10 to solve for x:
10x/10 < -20/10
x < -2
So, the solution to the inequality is x < -2.
