# How do you solve using gaussian elimination or gauss-jordan elimination, #6x+2y+7z=20#, #-4x+2y+3z=15#, #7x-3y+z=25#?

##### 1 Answer

#### Answer:

#### Explanation:

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

we get

Using a similar process on these two equations in

Select any one of the original equations to solve for
