#1**+2 **

w = weight of 1 cup

b = weight of empty bottle

2w + b = 360

5w + b = 600

Can you solve it from here?

Hint: start by subtracting the 2 equations.

#3**+2 **

2 cups + bottle = 360

5 cups + bottle = 600

3 cups of water = 1/3(600 - 360)

1 cup of water = 80 grams

Weight of bottle = 360 - 160 = 200 grams

#6**+1 **

Mass of 3 cups water = 600 g - 360 g = 240 g

Mass of 5 cups water = 240 g * 5 cups / 3 cups = 400 g

Mass bottle + 5 cups water = 600 g

Mass 5 cups water = 400 g

Mass of bottle = 200 g
