Question

If x+y+4z=6,3x+2y-2z=9,5x+y+2z=13 then write the augumented matrix form​

Answer 1

Answer:

Answer

Given equations are x+y+4z=6,3x+2y−2z=9,5x+y+2z=13

Therefore, D=∣∣∣∣∣∣∣∣1351214−22∣∣∣∣∣∣∣∣=1(4+2)−1(6+10)+4(3−10)

=6−16−28=−38

D1=∣∣∣∣∣∣∣∣69131214−22∣∣∣∣∣∣∣∣=6(4+2)−1(18+26)+4(9−26)

=6(6)−44+4(−17)=36−44−68=−76
