Incorrect. With x representing the unknown number of plums in each basket, the four baskets can be represented by 4x. Five plums being dropped out of the four baskets can be written as $\displaystyle{4}{x}-{5}\usepackage{cmbright}\Huge\$ . Because 15 plums remain, this expression is set equal to 15. Thinking about it this way, how can you represent this relationship?
