Question

9 – 2k = 25 what is k

Answer 1

k = -8

Explanation:

9 – 2k = 25

- 2k = 25 - 9

-2k = 16

k = 16 / -2

k = -8

Answer 2

k = - 8

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
