Question

solve for k if k=18-45/k​

Answer 1

K = 13.5 as per my calculations

Answer 2

Answer:

k = 15          ;            k = 3

Step-by-step explanation:

k = 18-45/k

Taking LCM,

k = (18k - 45)/k

k² = 18k - 45

k² - 18k + 45 = 0

Using Splitting the middle term,

k² -15k - 3k + 45 = 0

k(k - 15) - 3(k - 15) = 0

(k - 15)(k - 3) = 0

k - 15 = 0         ;      k - 3 = 0

k = 15                      k = 3
