Question

Solve the following pair of linear equations by graphical methord
1) 2x+y=5 and x+y=3

Answer 1

2x+y=5 ,x+y=3

While x+y=3 is multiple with 2 then we get a new equation

2x+2y=6

Then substrate the 2x+y=5 and 2x+2y=6

Then we get that y=1

give the value of y to 2x+y=5

then we get that x=2

So, x=2 and y=1

I hope you understood

Answer 2

Answer:

2x +y=5

y=2x-5

let x=0

x =0

y = -5 y=2x0-5 = -5

x, y= 0,-5

let y=1

x = -3 y=2x-5 =,1=2x-5,2x=-1-5,2x=-6,x=-6/2,x=-3

y= 1

x, y= -3 ,1

like this you solve and complete it
