Question

solve graphically the pair of linear equation x+2y=5 ,2x-4y=10​

Answer 1

Step-by-step explanation:

x+2y=5

taking x=5

5+2y=5

2y=5-5

2y=0

y=0

(5,0)

taking x=4

4+2y=5

2y=5-4

2y=1

y=1/2

(4,1/2)

taking x=3

3+2y=5

2y=5-3

2y=2

y=1

(3,1)

2x-4y=10

taking y=2

2x-4(2)=10

2x-8=10

2x=10+8

2x=18

x=9

(9,2)

taking y=4

2x-4(4)=10

2x-16=10

2x=10+16

2x=26

x=13

(13,4)

taking y=1

2x-4(1)=10

2x-4=10

2x=10+4

2x=14

x=7

(7,1)

Answer 2

Answer:

Both the equations are of the same line so there will be only one line
