Answer 1

Answer:

here is your answer mate...

Step-by-step explanation:

Hi there,

let tables = x

and chairs = y

Make two equations:

3x + 2y = 1900.....(1)

2x + 4y = 1800.....(2)

Multiply equation (1) by 2

6x + 4y = 3800.....(1)

2x + 4y = 1800

Subtract Equation (2) from (1)

4x = 2000

 

x = 500

Substitute x = 500 into

Equation (2)

2x + 4y = 1800

2(500) + 4y = 1800

1000 + 4y = 1800

4y = 1800 - 1000

4y = 800

y = 200

Therefore:

A Table costs Rs 500

A chair costs Rs 200

Hope this helps:-)
