Question

The coach of a cricket team buys 3 bats and 6 balls for 3900. Later, she buys another bat and 3 more balls of the same kind for 1300. solve using elimination method​

Answer 1

Answer:

Step-by-step explanation:      let rate of bat = xRs.

and rate of ball = y

3x+6y=3900...i)

and x+3y=1300...(ii)

or x=(1300−3y)  

now equation (i) can be written as

3(1300−3y)+6y=3900

3900−9y+6y=3900

∴y=0  

Ans:- x=1300
