(MATLAB) Use both rref() and the backslash method to find a solution to these sets of linear equations. In both cases double check your solution but substituting your values back into ONE of the original equations.

(a) Solve for the following set of linear equations:

2.0x1 + 5.0x2 + 1.0x3 + 3.0x4 + 4.0x5 1.0x6 = 0.0

2.0x1 1.0x2 5.0x3 2.0x4 + 6.0x5 + 4.0x6 1.0 = 0.0

1.0x1 + 6.0x2 4.0x3 5.0x4 + 3.0x5 1.0x6 = 6.0

4.0x1 + 3.0x2 6.0x3 5.0x4 2.0x5 2.0x6 = 10.0

3.0x1 + 6.0x2 + 4.0x3 + 2.0x4 6.0x5 + 4.0x6 = 6.0

2.0x1 + 4.0x2 + 4.0x3 + 4.0x4 + 5.0x5 4.0x6 + 2.0 = 0.0

(b) A good old-fashioned word problem. Dont forget use rref() and the backslash method to solve it. An Engineering textbook, a Physics textbook and a CompSci textbook can be purchased for $146 (yeah right!?). The Engineering textbook and the CompSci textbook can be purchased for

I need to know the steps to be able to do it in the program
