Question

solve the following system of linear equation graphically 2x+y-6=0,4x-2y-4=0

Answer 1

Here is your answer.....


2x+y-6=0

=>2x=6+y

=>x=6+y
___
2



4x-2y-4=0

=> 4x=2y+4

=>x=2y+4

________
4

Answer 2

2x+y-6=0.......eq.1
4x-2y-4=0.....eq.2
Substract eq.1 from eq. 2
4x-2y-4=0
-2x-y+6=0
Multiplying 2 in eq.2 and 4 in eq1 to balance
8x-4y-8=0
-8x-4y+24=0

-8y+16=0
-8y= - 16
8y=16
Y=2

Put the value of y in any one eq
Taking eq 1
2x+y-6=0
2x+2-6=0
2x-4=0
2x=4
X=2

Value of x and y = 2
