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).
