Answer:

0 < k < 2

Step-by-step explanation:

In the first quadrant, both x and y are positive, thus

• x > 0 and y > 0

• x = 2k, where k > 0

Substituting x with 2k into the second equation gives:

• 3x + 2y = 12
• 3*2k + 2y = 12
• 2y = 12 - 6k
• y = 6 - 3k

Given that y > 0:

• 6 - 3k > 0
• 2 - k > 0
• k < 2

By combining k > 0 and k < 2, we obtain:

• 0 < k < 2
