Question

The solution of the equation 2x-y-5=0

Answer 1

Answer:

(0,-5) (2.5,0) (1,-3) (3,1)

Step-by-step explanation:

• 2x - y - 5 = 0 is a linear equation in two variable
• It has infinite solutions

To find solutions for this equation put some values for x and y

Here, put x = 0,equation becomes

2 x 0 - y - 5 = 0

-y - 5 = 0

-y = 5

y = -5

Solution is ( 0,-5)

put y = 0,equation becomes

2x - 0 - 5 = 0

2x - 5 = 0

2x = 5

x = 5/2

x = 2.5

Solution is (2.5,0)

put x = 1,equation becomes

2 x 1 - y - 5 = 0

2 - y - 5 = 0

-3 -y = 0

- y = 3

y = -3

Solution is ( 1,-3)

put y = 1,equation becomes

2x - 1 - 5 = 0

2x - 6= 0

2x = 6

x = 6/2

x = 3

Solution is ( 3,1)
