Question

I Want a good answer ​

Answer 1

Given:

• 9x + y = 10      (1)
• 6x + 5y = 11     (2)

To Find:

• Whether (1,1) is a solution of given system of equations.

Solution:

Put (1,1) in equation (1)

→ 9(1) + 1 = 10

which is true.

⇒ (1,1) satisfies  9x + y = 10    

_____________________

Now, put (1,1) in  6x + 5y = 11

6(1) + 5(1) = 11

which is also true.

⇒ (1,1) satisfies 6x + 5y = 11

_____________________

Hence, we can say that (1,1) is a solution of

9x + y = 10  and 6x + 5y = 11

Final Answer:

Yes
