Question

Sunny bought 3kgs of onion and 2 kg of carrot for rupees 500 and sana bought 1kg of onions and 1 kg of carrot of rupees 200 represent the data in the form of linear equation in two variables

Answer 1

Step-by-step explanation:

let the 1kg of onion =x

and 1kg of carrot =y

now

he brought 3kg of onion and 2kg of carrot for 500

so we can say that

3x+2y=500

similarly

x+y=200. eq1

now we can solve it by elimination method or any method

now

3x +2y=500

(x+y=200)×3

3x+2y=500

3x+3y=600. now we can sub it

so

3x+2y=500

-3x-3y=-600

now -y=-100

or. y=100

and from eq 1

we know that

x+100=200. y=100

so x=100

so, x=100

and y=100
