Question

nd any four solutions of the equation
x- 2y + 5=0.

Answer 1

Step-by-step explanation:

Given:-

Equation is x -2y+5=0

To find:-

Find any four solutions of x- 2y + 5=0.

Solution:-

Given equation is x- 2y + 5=0.

(1)Put x=0 then

=>0-2y+5=0

=>-2y+5=0

=>-2y=-5

=>2y=5

=>y=5/2

The first solution=(0,5/2)

2)Put y=0 then

=>x - 2(0) +5 =0

=>x +5 = 0

=>x= -5

The second solution = (-5,0)

3) Put x= 3 then

=>3-2y+5=0

=>8-2y=0

=>2y=8

=>y=8/2

=>y=4

The third solution=(3,4)

4)Put y=1 then

=>x-2(1)+5=0

=>x-2+5=0

=>x+3=0

=>x=-3

The fourth solution=(-3,1)

Answer:-

The solutions are (0,5/2);(-5,0);(3,4);(-3,1)....

Pints to remember:-

• Given equation is a linear equation in two variables and it has infinitely number of many solutions

Answer 2

Answer:

hope it will help you

Step-by-step explanation:

Consider given the equation,

2x− y= 3

Put, x=0$$

2× 0− y= 3

−y= 3− 0

y= −3

Put again, x=1

2× 1− y= 3

−y= 3− 2

y= −1

Put again, x=2

2× 2− y= 3

−y= 3− 4

y= 1

Hence, this is the answer.
