Answer:
(5,1) is not a solution of the above system of equations.
Step-by-step explanation:
We are given a system of equations that are
- 5y = - 5 ......... (1) and
7x + 6y = 7 ........... (2)
So, solving equation (1) we get y = 1 and putting y = 1 in the equation (2) we get 7x = 7 - 6(1) = 1
⇒
So, it clear from the solution of the above equations i.e. (), we can say that (5,1) is not a solution of the above system of equations. (Answer)
