Consider the linear system

x+3y+4z = 37

x+4y+5z=40

5x+4y+z=19

To solve the linear system, we need to

A. Transform the system into the form x=…x=…, y=…y=… z=…z=….
B. Eliminate terms off the diagonal and make the coefficients of the variables on the diagonal equal to 1.
C. Divide by the leading coefficients.
D. Multiply and divide different rows to obtain a reduced system from which the answer may be easily seen.
E. Convert the system to an equivalent nonlinear system which may be solved numerically.
F. Invert the system.
G. All of the above
H. None of the above

(Select all that are correct.)

Solution

Solution is B,C and D
