Question 675900
3x -  y = 1
2x + 4y = 3 
:
this would be a 2 by 3 matrix
3 -1  1
2  4  3
:
the matrix value are made up of the coefficients of x and y and the number
:
In your calc set the size of the matrix(2 by 3) then enter each value just as it is above.
Follow the rules of your calc to solve
:
This came out
[A]
[(3 -1 1]
 (2 4 3)}
and the solution
rref([A])
[(1 0 .5); means x = .5
 [0 1 .5); means y = .5
:
Of course you could solve this using elimination of substitution too
