Answer:

Option (d) is correct.

Step-by-step explanation:

The equations are :

-x-2y=-4 .....(1)

3x+y=12 ....(2)

Equation (1) can be rewritten as follow :

-x = -4+2y

x = 4-2y .....(3)

So, to solve the above systems of equations, we must substitute the value of x from equation (3) in equation (2). Hence, the correct option is (D).

Answer:

infinite

Step-by-step explanation:

Put values

$\\ \sf\longmapsto 1a+3b+c=0$

$\\ \sf\longmapsto a+3b+c$

Hence for any values it has infinite number of solutions .
