Answer:
[tex]k=-7n-m[/tex]
Step-by-step explanation:
Given equation,
[tex]\frac{k+m}{-7}=n[/tex]
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,
[tex]k+m=-7n[/tex]
Subtract both sides by m,
[tex]k=-7n-m[/tex]
Which is the required equation.
