# In Exercises 23–28, let x, y, z, and w represent the population in millions of four cities A, B, C, and D, respectively. Express the given statement as an equation in x, y, z, and w. If the equation is linear, say so and express it in the standard form   a x + b y + c z + d w = k City D is actually a ghost town; there are no people living in it.

To determine

To calculate: The standard form of equation for the situation that the city D is a ghost town and there are no living people in it.
