I need help in doing these in MAT LAB

Question1 Use Matrices in MATLAB to solve the following system of linear equations 2z30 5x + 12y - 2x Question 2 Use the following matrix to answer the questions below. Define your matrix as V. 2 5 6 V-1-310-1 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
