0,5k=5 k+m=-5

To solve the equations you provided:

1. 0.5k = 5 To isolate k, you can multiply both sides of the equation by 2: 0.5k * 2 = 5 * 2 k = 10

2. k + m = -5 To isolate m, you can subtract k from both sides of the equation: k + m - k = -5 - k m = -5 - k

So the solutions to the equations are: k = 10 m = -5 - k = -5 - 10 = -15
