Answer: Answer in the picture below!
3 − 3 k + 7 k = 5 b 3 + 4 k = 5 b 4 k = 5 b − 3 k = 4 5 b − 3
The solution for k in the equation 3 − 3 k + 7 k = 5 b is k = 4 5 b − 3 . We combined like terms, isolated k , and divided to get the final answer. This approach clearly illustrates the steps involved in solving linear equations.
