Answer:
Option- one is correct.
The given system of equations have one solution that is (7,-21)
Step-by-step explanation:
Given system of equations are
Now to the solution:
To solve the given system of equations using substitution method.
That is substitute equation(1) in equation (2) we get
(here y=-3x)
(adding the like terms)
Therefore x=7
Now substitute x=7 in equation (1) we get
Therefore the solution is (7,-21)
Therefore Option- one is correct.
The given system of equations have one solution that is (7,-21)
