Final answer:
To solve the equation 5+kx=17 for x, subtract 5 from both sides and then divide by k. To solve the equation 9x−2c=k for x, add 2c to both sides and then divide by 9. The correct answer is option a) x=2, c=8.
Step-by-step explanation:
To solve the equation 5+kx=17 for x:
- Subtract 5 from both sides to isolate the kx term: kx = 17 - 5 = 12
- Divide both sides by k to solve for x: x = 12/k
To solve the equation 9x−2c=k for x:
- Add 2c to both sides to isolate the 9x term: 9x = k + 2c
- Divide both sides by 9 to solve for x: x = (k + 2c)/9
Therefore, the correct answer is option a) x=2, c=8.
