Question

solve the system of equations : 2p+q+2r+s=6 ; 6p-6q+6r+12s=36 ;4p+3q+3r-3s=1 ; 2p+2q-r+s=0 find out whether they are consistent or inconsistent ​

Answer 1

Answer:

Given: 6p+4q-r+ 3, 2r-5p -6,11q

7p+2r - 1 and 2q - 3r +4

To add the given terms we have to add coefficient of like terms:

.. (6p+4q-r+)3 + (2r - 5p - 6) + (11q -

7p+2r-1)+(2q - 3r + 4)

= (6-5-7+0)p+(4+0+11+ 2)q + (−1+ 2+2-3)r +(3-6-1+4)

= -6p+17q+Or +0

= 17q-6p

hope this helps ❤️
