The two fundamental approaches to constrained allocation problems are ________.

Given a scheduling equation W = D * U, if the equation for task A is initialized so that W = 40d, D = 10d, and U = 4 resources, and task A is an effort-driven activity, correctly balance this equation if the value for U is changed from 4 to 5. To balance the equation, the altered variable and its new value are ________.
