Question

The coach of cricket team buys 7 bats and 6 balls = 3800 rs and they buy 3 bats and 5balls for 1750 rs form linear equation to represent this
​

Answer 1

Answer:

7x + 6y = 3800 equ (1)

3x + 5y = 1750 equ (2)

cost of one bat = x = 500

cost of one ball = y = 50

Step-by-step explanation:

let the number of bats be x

let the number of balls be y

7x + 6y = 3800 equ (1)

3x + 5y = 1750 equ (2)

multiply equ (1) with 3 and equ (2) with 7

21x + 18y = 11400 equ (3)

21x + 35y = 12250 equ (4)

subtract (4) - (3)

17y = 850

y = 850/17

y = 50

substitute y = 50 in equ (2)

3x + 5(50) = 1750

3x + 250 = 1750

3x = 1750 - 250

3x = 1500

x = 1500/3

x = 500

cost of one bat = x = 500

cost of one ball = y = 50

Hope you get your answer
