Question

The system of eqns 2x+2y-3z = 1,4x+4y+ Z = 2 , 6x+6y-z=3 has

Answer 1

Answer:

SYSTEM OF EQUATION HAS INFINITE SOLUTION

Step-by-step explanation:

GIVEN THE SYSTEM OF EQUATIONS:

2X+2Y-3Z-1=0

4X+4Y+Z-2=0

6X+6Y-Z-3=0

which can be written in matrix form as:

          2  2  -3  :  -1

          4  4   1   :  -2

          6  6  -1  :   -3

R2⇒R2-R1

R3⇒R3=R1

        2 2 -3 : -1

        0 0 7 :  0

        0 0 8 :  0

⇒ρ(A:B)≠ρ(A)
