hey, could you help me to solve this Gaussian-Jordan method?

Problem For the following systems of equations, use the Gauss-Jordan method to determine whether the system has no solution, a unique solution, or an infinite number of solutions. Indicate the solution (i.e., what each variable equals) if it is unique. Part a: -12 +14 3.01 2 21 +13 +423 + +2.25 = 8 = 2 = 4 +3.02 +34 Part b: 1 0 -3 0 1 1 0 2 -2 1 2 8 2 -2 -2 8 2 3 -1 10 3 -10 12
