Question

-k - 17 = -5 - K - 12

Answer 1

All real numbers are solutions.

Explanation:

−k−17=−5−k−12

−k+−17=−5+−k+−12

−k−17=(−k)+(−5+−12)

−k−17=−k+−17

−k−17=−k−17

−k−17+k=−k−17+k

−17=−17

−17+17=−17+17

0=0

Answer 2

∴ K = 0

Explanation:

- K -17 = -5 - K -12

- K + K = - 5 - 12 + 17

0 K = -5 + 5

0 K = 0

∴ K = 0
