\begin{aligned} & -5y=-5 & 7x+6y=7 \end{aligned}


−5y=−5
7x+6y=7


is (5,1)(5,1)left parenthesis, 5, comma, 1, right parenthesis a solution of the system?

(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)
