Hello, I've been given the following equation to solve. I've even been told the answer - as being 5400 - but I am not sure how one would go about solving for the variable "D", which is on both sides of the equation, and this variable seems "difficult to get at". Thank you in advance for any possible advice.
100 + (0.1 * D) = 3600 - 1000 - [0.426 * (10,000 - D)]
100 + (0.1 * D) = 3600 - 1000 - [0.426 * (10,000 - D)]
