Question

solve for n.

n - 18 < -7

Explanation:

Step1: Add 18 to both sides

To isolate \( n \), we add 18 to both sides of the inequality \( n - 18 < -7 \). This gives us \( n - 18 + 18 < -7 + 18 \).

Step2: Simplify both sides

Simplifying the left side, \( n - 18 + 18 \) becomes \( n \). Simplifying the right side, \( -7 + 18 \) equals \( 11 \). So we have \( n < 11 \).

Answer:

\( n < 11 \)
