Question

obtain a pair of linear equation in two variables​

Answer 1

Answer:

let the cost of 1 kg tea be x

and the cost of 1 kg tea be y

Step-by-step explanation:

then 2x + 3y = 200

and 4x + 3y = 350

Answer 2

Here Is Your Ans ⤵

***

Let The cost Of 1 kg Tea be X

And The cost of 1 kg Sugar Be Y

According To The Question

4X + 3Y = 350 ⬅Equation 1

2X - 3Y = 200⬅Equation 2

Subtract Equation 1 and 2

We get ,

2X = 150

X = 75

Put the value of X in Equation 2

2 × 75 + 3Y = 200

150 + 3Y = 200

3Y = 50

Y = 50 / 3 = 16.66667

Hence ,

The Price Of tea and sugar is ₹75 and ₹16 per Kg
