Question

2x+y=8 , x+y=5 solve graphically​

Answer 1

Given

➝2x + y = 8 (i)

➝x + y = 5 (ii)

Now take (i)eq

➝2x + y = 8 (i)

When x = 0

➝2(0) + y = 8

➝y = 8

we get (0,8)

When y = 0

➝2x + 0 = 8

➝2x = 8

➝x = 4

we get (4,0)

Now Take (ii)eq

➝x + y = 5 (ii)

When x = 0

➝0 + y = 5

we get (0,5)

when y = 0

➝x + 0 = 5

➝x = 5

we get (5,0)
