[" (n-sistent of the renterit "],[5x+3y+7z=4],[3x+26y+2z=9],[7x+2y+10z=5]

By using the principle of matrix, show that the following system of equations has infinite solution: 5x+3y+7z=4, 3x+26y+2z=9, 7x+2y+10z=5 .

3x+4y+7z=4, 2x+y+ 3z= 3, x + 2y +3z =8.

The system 2x + 3y + z= 5, 3x + y + 5z =7, x + 4y -2z=3 has

Write down the terms of the expression: 8x^4y-7x^3y z+4/3x^2y z^2- 5 x y z . What is the coefficient of x^2 in the term 4/3x^2y z^2?

[[x+y+z],[x+z],[y+z]]=[[9],[5],[7]]
