I'm going to assume this is the eqaution:
(3/5)k - (1/10)k = (1/2)k + 1
Get all the variables on the left by subtracting (1/2)k from both sides.
(3/5)k - (1/10)k - (1/2)k = (1/2)k - (1/2)k + 1
(3/5)k - (1/10)k - (1/2)k = 1
Factor out the k and simplify the left side
k(3/5 - 1/10 - 1/2) = 1
k(6/10 - 1/10 - 5/10) = 1
k(0) = 1
No Solution :)
