Determine by Inspection 1 e without performing any calculations whether a linear system with the given augmented matrix has a unique solution infinitely many solutions or no solution 3 4 01 1 1 4 3 1 1 2 8 6 2 0 unique solution O Infinitely many solutions Ono solution Justify your answer O The matrix can be rewritten in row echelon form with one free variable The matrix can be rewritten in row echelon form with two free variables O This system is a homogeneous system with four variables and only three equations so the rank of the matrix is at most 3 and thus there is at least one free variable O The matrix can be rewritten so that you have a row 00 00 a with a 0 OTHE no free variables
