Question

5 pens and 6 pencils together cost Rs9 and 3 pens and 2 pencils cost Rs 5. Find the cost ofpen and 1 pencil.​

Answer 1

Answer:

let the cost of pen = X

let the cost of pencil = y

5 pens + 6 pencils = 9

5x + 6y = 9

3 pens + 2 pencils = 5

3x + 2y = 5

5x + 6y = 9

3x + 2y = 5

5x + 6y = 9

3 ( 3x + 2y = 5)

5x + 6y = 9

9x + 6y = 10

5x + 6y = 9

-9x - 6y = -10

-4x = -1

X = -1/-4

X = 1/4

3x + 2y = 5

3( 1/4 ) + 2y = 5

3/4 + 2y = 5

2y = 5 - 3/4

2y = 20 - 3 / 4

2y = 17/4

y = 17 / 4 × 2

y = 17 /8
