How can I solve the following systems using Gaussian elimination method, w+2x-y=4, x-y=3 , w+2x-2y=7 2u+4v+w+7x=7?
1 answer:
Move the variable to the left-hand side and change its sign
Collect like terms
Divide both sides of the equation by
Write the solution in parametric form
The next to one is
Move the variables to the right-hand side and change their signs
Divide both sides of the equation by
Write the solution in parametric form
U = 7/2 -2v - 1/2w-7/2x, ver,
Wer , xer
