Using Matlab, please help me with this

You have to turn in a diary file named lastname_lab5.txt (Make sure that your submission is .txt and do not compress the file(s).) (1) Question 1 Start a diary file. For the following system of equations, use the command ezplot or rref or the backslash operator to determine if the linear system has a solution? Many solution? No solution? Indicate your answer with the comment '\%' or edit the diary file. If there is a solution, try to solve for the solution using either of the backslash operator and the reduced row echelon function. (a) x+2y=32x4y=6 (b) x7y=115x+2y=18 (c) 2x14.5x2+3.1x3x1+x2+x3x16.2x2+x3=4.2=5.1=1.3 (2) Question 2 Set up the linear system to solve the following problem. Use the comment '\%' to write out the equations. Balance the following chemical reaction equation: aC2H6+bO2cH2O+dCO2 Explicitly write the augmented matrix, how you solve for the coefficient using rref, and the balanced equation in your diary
