The unique solution is x and X3 = The system has infinitely many solutions. The solution is x Ов. (Simplify your answers. Type and x3 t. X2 = expressions using t as the variable.) The system has infinitely many solutions. The solution is x, ,x2 s, and x =t. O C. (Simplify your answer. Type an expression using s and t as the variables.) O D. There is no solution.
