Help me solve for K?

Question

-2/7k+1/6=-7-4/9k

Answer 1

-2/7k+1/6=-7-4/9k

-2/7k+4/9k=-7-1/6

use 126 as a lcd

-36k+56k= -43/6

20k=-903

k=-45 3/20

Answer 2

4/9k-2/7k = -7-1/6

(10/63k = -7 1/6)/ 10/63

k= - 45 3/20

or k = - 903/20

Answer 3

I will show you the steps, but you will need to get the answer.

-2/7k + 1/6 = -7 - 4/9k  

-2/7k +4/9k = -7 - 1/6  (combine the like terms)

the denominator for -2/7 and 4/9 would be 63.

the denominator for -7 and -1/6 would be 6.

-18/63k + 28/63k = -42/6 - 1/6

10/63k = -43/6  (Now divide both sides by 10/63) and you will get your answer.

Answer 4

get the k''s on one side so

-2/7k + 4/9k = -7 - 1/6

18/63k + 28/63k = -7 1/6

46/63 k = -43/6

46k = (-43*63)/6

k = -9.81

Answer 5

I am assuming the k's are located in the denominator.

-2/7k + 1/6 = -7 - 4/9k

-2/7k + 4/9k = -7 - 1/6

-2(9)/(7)(9)k + 4(7)/(9)(7)k = -42/6 - 1/6

(-18+28) / 63k = - 43/6

10/63k = -43/6

(10)(6) = (-43)(63)k

k = 60 / (-43)(63)

solve the rest yourself, and double-check it is correct.
