I don't know what to type into Matlab to achieve the answer

4. Linear Algebra: The dissolution of copper sulfide in aqueous nitric acid is described by the following chemical equation: aCuS + bN03 +cH+ dCu2+ + eso- +fNO+gH20 Where the coefficients a, b, c, d, e, f, and g are the numbers of the various molecules participating in the reaction and are unknown. The unknown coefficients are determined by balancing each atom on left and right and then balancing the ionic charge. The resulting equations are: a = d, a = e, b = f, 3b = 4e + f +g, c = 2g, -b + c = 2d 2e Assuming that a=6, solve the system of equations using linear algebra. (You may either set a=6 in the above equations, so that there are now just 6 unknown variables for the 6 equations, or you can make a=6 the seventh equation. Either way, you should arrive at the same solution. Display the answer in the command window
