The reduced row-echeion form of the augmented matrix for a system of linear equabions with variables x1. . . xy is given below. Determine the solusions for the sysfem and enser them below [1030014522] If the system has infintely many solutions, select "The system has at least one solution". Your answer may use expressions involving the parameters r, s, and f. The system has at least one solution x1=0x2=0x3=0x4=0
