Question

5k + 30 = -20 - 5k
Solve for K.

Answer 1

-5 = k

Explanation:

5k + 30 = -20 - 5k

5k + 30 + 20 = 5k + 50

-20 - 5k + 20 = -5k

5k + 50 = -5k

5k + 50 - 5k = 50

-5k - 5k = -10k

50 = -10k

50 / -10 = -5

-10k / -10 = k

-5 = k

Answer 2

5k + 30 = -20 - 5k

5k + 5k = -20 - 30

10k = -50 / : 10

k = -5
