Need to do this in MATLAB

Question 1 Use Matrices in MATLAB to solve the following system of linear equations. -4x + 3y + z = -18 5x + 12y-2z = 30 2a- Question2 Use the following matrix to answer the questions below. Define your matrix as V V3 10 -1 3 -9 1 For each part, show the result and explain, in English, how MATLAB calculated it. Answers should include whether it is Matrix operations or Element-by-Element operations. a. V*V b. V.V d. det (V) e, inv(V) Question 3 Define A, B, and C in MATLAB and perform the operations. Note: Extra credit will be awarded if you can have MATLAB show that the operations are equivalent. Full credit will be awarded if you can verify yourself that they are. If MATLAB is not used to show their equivalence, you will need to write a statement in English about the equivalency of the operations. Notice the difference in part e - you will need something written whether MATLAB can show equivalence or not. 1-3 5 0 -2 1 3 4 -1 -2 06 2 -7 1 a. Calculate A Band B+ A to show that addition of matrices is commutative. b. Calculate A (B+C) and (A B) +C to show that addition of matrices is associative .Calculate 3(A +C) and 3A+3C to show that, when matrices are multiplied by a scalar, the multiplication is distributive d. Calculate A * (B + C) and A * B + A * C to show that matrix multiplication is distributive. e.Calculate AB and B A. Are they the same? Why or why not
