Question

Write four solution of equation x-y =9

Answer 1

Answer:

1. x=1, y= -8
2. x=0, y= -9
3. x=2, y= -7
4. x=3, y= -6

Step-by-step explanation:

•put x=1

x-y=9

1-y=9

-y=9-1

-y=8

y= -8

•put x=0

x-y=9

0-y=9

-y=9

y=-9

•put x=2

x-y=9

2-y=9

-y=9-2

-y=7

y=-7

•put x=3

x-y=9

3-y=9

-y=9-3

-y=6

y=-6

Answer 2

Answer:

The four solutions of the given equation are: (0,-9),(9,0),(1,-8),(2,-7)

Step-by-step explanation:

Given: $x-y =9$

We have to write four solutions to the above equation.

• As we can see, we only have one equation, so to find the solution of the given equation, we will put the different values of x and y in the given equation.

We are solving in the following way:

We have,

$x-y =9$

a) putting x=0 we get;

$=>0-y=9\\=>-y=9\\=>y=-9$

b)Putting y=0, we get;

$=>x-0=9\\=>x=9$

c) putting x=1 we get;

$=>1-y=9\\=>-y=9-1\\=>-y=8\\=>y=-8$

d) putting x=2 we get;

$=>2-y=9\\=>-y=9-2\\=>-y=7\\=>y=-7$

Hence, the four solutions of the given equation are: (0,-9),(9,0),(1,-8),(2,-7)
