Question

Solve graphically 2x+y=6 and 4x-2y=4

Answer 1

Step-by-step explanation:

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
