Question

3c - 15 = -45

Explanation:

Step1: Add 15 to both sides

To isolate the term with \( c \), we add 15 to both sides of the equation \( 3c - 15 = -45 \). This gives us \( 3c - 15 + 15 = -45 + 15 \), which simplifies to \( 3c = -30 \).

Step2: Divide by 3

Now, we divide both sides of the equation \( 3c = -30 \) by 3 to solve for \( c \). So, \( \frac{3c}{3} = \frac{-30}{3} \), which simplifies to \( c = -10 \).

Answer:

\( c = -10 \)
