Question

x+2y=4 ;2x+4y=12 solve this linear equation by graphical method and normal method also​

Answer 1

Answer:

x+2y=4

2x+4y=12

Solution:

Step 1: Find points to plot x+2y=4

Put x=0

0+2y=4

y=2

let it is point A(0,2)

Put y=0

x+0=4

x=4

let it is point B(4,0)

Plot points on graph,make a straight line by joining these points.

Step 2: Find points to plot 2x+4y=12

Put x=0

0+4y=12

y= 3

let it is point C(0,3)

Put y=0

2x+0=12

x=6

let it is point D(6,0)

Plot points on graph,make a straight line by joining these points.

Graph is attatched.

It is clearly shown that both the lines are parallel,they never meet each other.

Therefore,these linear equation has no solution.
