Answer 2

We are given:

K - L = M ...(1)

K + K = LM ...(2)

We can solve for K in equation (1):

K = M + L ...(3)

Substituting equation (3) into equation (2), we get:

M + L + M + L = LM

2M + 2L = LM

2(M+L) = LM

Dividing both sides by 2 and rearranging:

M + L = LM/2

Now we can substitute the value of LM/2 into the expression K+L+M:

K+L+M = (M+L) + M = 2M + L

Therefore, the value of K+L+M is 2M + L.
