Answer:

k = -0.4

Step-by-step explanation:

Step 1: Write equation

2k + 9 = 7 - 3k

Step 2: Solve for k

  1. Add 3k to both sides: 5k + 9 = 7
  2. Subtract 9 on both sides: 5k = -2
  3. Divide by 5 on both sides: k = -2/5
  4. Convert to decimal: k = -0.4

Step 3: Check

Plug in k to verify it's a solution.

2(-0.4) + 9 = 7 - 3(-0.4)

-0.8 + 9 = 7 + 1.2

8.2 = 8.2
