Question

Solve the equation or formula for the variable indicated.



3c−9d=12,forc

Answer 1

To solve the equation \( 3c - 9d = 12 \) for \( c \), follow these steps:

1. **Isolate the term involving \( c \)**:
\[
3c = 12 + 9d
\]

2. **Divide by 3 to solve for \( c \)**:
\[
c = \frac{12 + 9d}{3}
\]

3. **Simplify the expression**:
\[
c = 4 + 3d
\]

So, the solution for \( c \) is:
\[
c = 4 + 3d
\]
