Equation Array Object

The Equation Array object consists of one or more equations grouped as an object. Within the equation array, multiple components can be aligned to each other. Examples of equation arrays are:

and

Equation arrays can have "maximum distribution" such that they occupy the entire width of the column that contains them, as in:

Or, they can have "object distribution" such that there is even spacing between the margin and text (distance1 = distance2 = distance 3):
