Answer:
Ravi had 355ml water to begin with.
Step-by-step explanation:
Given that,
amount of water that Gwent pour in Ravi = 256 ml
amount of water that Henry pour in Ravi = 189 ml
amount of water after each have poured = 800 ml
suppose amount of water ravi had before both poured water in it = x
Equation
256 + 189 + x = 800
445 + x = 800
x = 355ml
Initially ravi had 335ml of water.

Step-by-step explanation:
3(15.9 - 3.9)
3 · (15.9 - 3.9)
3(15.9) - 3(3.9)
47.7 - 3(3.9)
47.7 - 11.7

Answer:
Multiply the first equation by 4.
Step-by-step explanation:
4(x+y=3) which gives
4x+4y=12
and
4x-y=7
Then subtract the two equations and the x variable will be eliminated.
