Answer:
k=13
Step-by-step explanation:
19 + 12k = –k − 20
19+20=39=13k
k=13
Answer: -3
Step-by-step 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
