Question

If 2k - 3 = 9 (k+7)-3 then k is ????

Answer 1

Answer:

K = -9

Step-by-step explanation:

2k-3 = 9(k+7)-3

2k-3 = 9k+63-3

2k-3 = 9k+60

2k-9k = 60+3

-7k = 63

-k = 9

k = -9

Answer 2

Answer:

k= -9

Step-by-step explanation:

2k-3=9k+63-3     [expand the 9(k+7) first]

2k-9k=63-3+3     [put the like terms together]

-7k=63                 [do the simple math]

k= 63 ÷ by -7

k=-9
