Question

solve for c. 2(c + 20) = 18

Explanation:

Step 1: Divide both sides by 2

To isolate the term with \( c \), we divide both sides of the inequality \( 2(c + 20)>18 \) by 2. This gives us \( \frac{2(c + 20)}{2}>\frac{18}{2} \), which simplifies to \( c + 20>9 \).

Step 2: Subtract 20 from both sides

Next, we subtract 20 from both sides of the inequality \( c + 20>9 \) to solve for \( c \). So, \( c + 20 - 20>9 - 20 \), which simplifies to \( c>- 11 \).

Answer:

\( c > -11 \)
