Following that, the notebook must use a manual method of your choice to solve for x,y, and z for the following system of equations. 3x+4y+3z=109x10y10z=114x+15y+18z=37 Do not use any of the automated functions of the SciPy or similar library to construct the solution. Do it the old-fashioned pencil and paper way. If you have forgotten how to do that, see Systems with three variables for an explanation of a manual solution for three equations. The notebook must include Markdown sections that explain each step in the solution of the problem. Pretend that you are a middle school teacher showing your students how to do this for the first time. The notebook must also include a section that confirms that your solution is correct Present your solution in the following format x=??y=??z=?? where the actual solution values replace the ?? shown above
