Question

find the solution of the following pair of linear equation by the graphial method 2x+y=6 and 2x-y=2​

Answer 1

Answer:

2x+y=6

2x-y= 2

4x=8

x= 2

2(2)+y=6

y= 6-4

y=2

Answer 2

Answer:

2x+y=6

if x=1

2(1)+y=6

2+y=6

y=6-2

y=4

(1, 4)

2x-y=2

if x=2

2(2)-y=2

4-y=2

-y=2-4

-y= -2

y=2

(2, 2)

hope it helps u..
