Question

verify the following equations are consistent . if it is consistent find the solution x-4y-3z=-16 , 4x-y+12z=48 , 5x-5y+3z=0​

Answer 1

Step-by-step explanation:

x-4y-3z=-16

let x=0,y=4and z=0

0-4×4-3×0=-16

0-16-0=16

-16=-16

4x-y+12z=48

let x=0,y=0 and z=4

4×0-0+12×4=48

0-0+48=48

48=48

5x-5y+3z=0

let,x=3,y=3 and z=0

5×3-5×3+3×0=0

15-15+0=0

0+0=0

0=0
