Final answer:
The solution to the equation 2(k–5)+2k=5k+5 is k = -15. This value of k was obtained by distributing, combining like terms, and isolating k. However, this solution is not listed among the options provided, suggesting there may be a typo in the original question.
Step-by-step explanation:
The student is asking to solve the equation 2(k–5)+2k=5k+5. To find the value of k, we need to simplify and solve for k. Here's the step-by-step solution:
- Distribute the 2 into the parentheses: 2k - 10 + 2k = 5k + 5.
- Combine like terms on the left side: 4k - 10 = 5k + 5.
- Get all the k terms on one side by subtracting 4k from both sides: -10 = k + 5.
- Finally, subtract 5 from both sides to solve for k: k = -15.
It looks like there may have been a typo in the options provided since k = -15 is not listed. Be sure to double-check the original equation for any errors.
