Question

39.* a. Use MATLAB to solve the following equations for x, y, and z as functions of the parameter c.
6x + 3y + z = 13c
x - 5y - 2z = 11c
7x + 3y - 5z = 10c
Plot the solutions for x, y, and z versus c on the same plot, for -10<= c <=10.

Answer 1

Are you supposed to write a code that does this or just use matlab to solve it?

Answer 2

If you are supposed to write the code, look up "forward sweep" and "backward substitution" by setting your equations into a matrix and a vector for your x y and z values.

If not, then look up the backward slash operator in matlab that does that Gaussian elimination for you.
