To solve for \( c \) in the equation
\[ -14 = -21 + 11c, \]
start by isolating the term with \( c \).
- First, add 21 to both sides of the equation:
\[ -14 + 21 = 11c. \]
This simplifies to:
\[ 7 = 11c. \]
- Next, divide both sides by 11 to solve for \( c \):
\[ c = \frac{7}{11}. \]
So, the solution is
\[ c = \frac{7}{11}. \]
