-2k=13 k+m=8

To solve the equation -2k=13, you need to isolate the variable k. To do this, divide both sides of the equation by -2:

-2k / -2 = 13 / -2

k = -13/2 or k = -6.5

For the equation k+m=8, you can rearrange it to solve for m. Subtract k from both sides of the equation:

k+m-k = 8 - k

m = 8 - k

Now substitute the value of k from the previous equation into this one:

m = 8 - (-6.5)

m = 8 + 6.5

m = 14.5

Therefore, the solutions for the system of equations are k = -6.5 and m = 14.5.
