Asystem of linear equations with fewer equations than unknowns is sometimes called an underdetermined system. can such a system have a unique solution? explain. choose the correct answer below. a. yes, it can have a unique solution. because there are more equations than variables, there are no free variables. if the system is consistent and there are no free variables, the solution set contains a unique solution. if the system is inconsistent, there is no solution. b. no, it cannot have a unique solution. because there are more variables than equations, there must be at least one free variable. if there is a free variable, the solution set contains a unique solution. c. no, it cannot have a unique solution. because there are more variables than equations, there must be at least one free variable. if the linear system is consistent and there is at least one free variable, the solution set contains infinitely many solutions. if the linear system is inconsistent, there is no solution. d. yes, it can have a unique solution. because there are more variables than equations, there must be at least one free variable. if the linear system is consistent and there is at least one free variable, the solution set contains either a unique solution or infinitely many solutions. if the linear system is inconsistent, there is no solution.
