Question

Ruby bought 3 kg of onions and 2 kg of carrot for 500. Sana bought 1 kg of onions

and 1 kg of carrot for 200. Represent the data in the form of pair of linear equations in

two variables.​

Answer 1

ANSWER:

from first condition

3x + 2y = 500

from second condition

1x + 1y = 200

therefore,

3x + 2y = 500

1x + 1y = 200

is the form of pair of linear equation

Answer 2

Answer:

let the fixed value of 1 kg onion be x

and let the fixed value of 1 kg carrot be y

A/Q

for ruby

3x + 2y = 500

and for sana

x + y = 200

this is the two equations of linear equations
