Question

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

Answer 1

Answer:

Step-by-step explanation:

First we will find the value of a in the given equation

2x+ay=5

Where x=1 and y= - 1

2(1) +a(-1) =5

2-a=5

-a=5-2

-a=3

a=-3

Now we got equation 2x-3y=5

First step

Let y=3

2x -3(3)=5

2x-9=5

2x=5+9

2x=14

x=14/2

x=7

Second solution

Let y=1

2x-3(1) =5

2x-3=5

2x=5+3

2x=8

x=8/2

x=4

Therefore the two solutions are (7, 3) and (4, 1)

Answer 2

Answer:

therefore the two solution are (7,3) and (4,1)
