9 - 2k = 25 what is k

k = - 8

Step-by-step explanation:

Subtract 9 from both sides to get the constants on one side and the variables on the other

9 - 2k = 25

- 2k = 25 - 9

Simplify

- 2k = 16

Divide by - 2 on both sides to isolate the variable, then simplify once more.

- 2k / - 2 = 16 / - 2

k = 16 / - 2

k = - 8

k = - 8

Step-by-step explanation:

9 - 2k = 25

- 2k = 25 - 9

-2k = 16

k = 16 / - 2

k = - 8
