Question

Find the value of a for which the equation 2x + ay = 5 has (1, -1) as a solution. Find two more solutions for the equation obtained

my answer is coming this
For the equation 2x+ay=5 , The solution is x=1 and y=-1, So, 2×1+a×-1=5, 2-a=5, 2-5=a, -3=a , So the value of a is -3. Two more solution for this equation are (5, 5/3), (3, 1/3)

is it correct
I want to know that my answer is correct or not​

Step-by-step explanation:

2x+ay=5 has (1,−1) as its solution

∴2×1+a(−1)=5

⇒2−a=5

⇒a=−3

∴2x−3y=5

other solutions are (10,5) and (25,15)

∵2×10−3×5=20−15=5

and ∵2×25−3×15=50−45=5
