Answer:
k = -0.4
Step-by-step explanation:
Step 1: Write equation
2k + 9 = 7 - 3k
Step 2: Solve for <em>k</em>
- Add 3k to both sides: 5k + 9 = 7
- Subtract 9 on both sides: 5k = -2
- Divide by 5 on both sides: k = -2/5
- Convert to decimal: k = -0.4
Step 3: Check
<em>Plug in k to verify it's a solution.</em>
2(-0.4) + 9 = 7 - 3(-0.4)
-0.8 + 9 = 7 + 1.2
8.2 = 8.2
