-2k=13 k+m=8

To solve the equation -2k = 13, we need to isolate k.

Divide both sides of the equation by -2:

(-2k) / -2 = 13 / -2

This simplifies to:

k = -6.5

So, the solution to the equation -2k = 13 is k = -6.5.

Now, let's solve the equation k + m = 8 for m.

Since we know that k = -6.5, we can substitute this value into the equation:

-6.5 + m = 8

Add 6.5 to both sides of the equation:

-6.5 + 6.5 + m = 8 + 6.5

This simplifies to:

m = 14.5

Therefore, the solution to the equation k + m = 8 is m = 14.5.
