How do you solve using gaussian elimination or gauss-jordan elimination, #6x+2y+7z=20#, #-4x+2y+3z=15#, #7x-3y+z=25#?
Gaussian elimination is a process of solving simultaneous equations in more than two variables by repeatedly adding and/or subtracting the equations.
Observing that there is an element
If we add
Using a similar process on these two equations in
