Find the solution of the following pairs of linear equ
on of the following pairs of linear equation by the graphical
method :
2x+y = 6
2x-y = 2​

Answer 1

we have ,2x+y=6

y=6-2x

so x=0

y = 6-2*0,

y = 6-0=6

y = 6

so x=3

y = 6-2*3

y = 6-6=0

y = 0

so x=2

y = 6-2*2

y = 6-4=2

y = 2

x=0,3,2

y=6,0,2

we have,2x-y=2

y=2+2x

so x=0

y=2+2*0

y=2+0=2

y=2

so x=1

y=2+2*1

y=2+2=4

y=4

so x=2

y=2+2*2

y=2+4=6

y=6

x=0,1,2,

y=2,4,6
