Let's go through the steps to isolate \( x \) in the equation \( 5x - c = k \).
Step 1: Isolate the variable \( x \)
To isolate \( x \), we first want to get rid of \( -c \) on the left side. We can do this by adding \( c \) to both sides of the equation:
\[ 5x - c + c = k + c \] This simplifies to: \[ 5x = k + c \]
Step 2: Isolate the variable \( x \) again
Next, we need to get \( x \) by itself, so we divide both sides of the equation by \( 5 \):
\[ \frac{5x}{5} = \frac{k + c}{5} \] This simplifies to: \[ x = \frac{k + c}{5} \]
So the final answer is:
\[ x = \frac{k + c}{5} \]
(Note: Your original final answer stated \( x = \frac{k + c}{5} \), but make sure to add \( k \) and \( c \) together in the numerator, as done above. The correct final answer reflects that.)
