Answer:
\(k=-7n-m\)
Step-by-step explanation:
Given equation,
\(\frac{k+m}{-7}=n\)
For finding the equation for k,
We need to isolate k in the left side of the equation,
Multiply both sides of the above equation by -7,
\(k+m=-7n\)
Subtract both sides by m,
\(k=-7n-m\)
Which is the required equation.
