The dual of a maximization problem with three decision variables and two constraints will be a maximization problem with only two decision variables in the objective function.

The dual of a maximization problem is a minimization problem, and the number of decision variables in the dual problem corresponds to the number of constraints in the primal problem, so the dual will have two decision variables, not because it's a maximization but because it's a minimization problem with two constraints from the primal problem.
