Answer: -3

Explanation:

Let's solve your equation step-by-step.

19+12k=−k−20

Step 1: Simplify both sides of the equation.

19+12k=−k−20

19+12k=−k+−20

12k+19=−k−20

Step 2: Add k to both sides.

12k+19+k=−k−20+k

13k+19=−20

Step 3: Subtract 19 from both sides.

13k+19−19=−20−19

13k=−39

Step 4: Divide both sides by 13.

13k /13 = −39/13
