When specifying linear constraints, the modeler must take into account the unit specification of the decision variables so that the units represented by the left side of the constraints are consistent with the units represented by the right side of the constraints.

This is true because the left side of a linear constraint typically represents a linear combination of decision variables with coefficients representing different units, and this linear combination must equal the right side of the constraint, which also has a specific unit in which it is measured. For example, if the decision variable represents quantities of a certain product, the coefficient in the constraint that represents the product's price must be in the same unit as the constraint's right side, which represents the budget or cost limit.
