dipesh pose la question : consider the system of equations
x-6y+2z=5
2x-9y-z=14
4x+12y-3z=19 by reducing the augm matrix to row echelon form, find
the solution to the equation.
leaving the first two equations the third is changed to -3x+6y+14z=-31
show the equations have infinitely many solutions and give a general
formula for them Penny Nom lui répond. |
