Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
= 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
= 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.

MARK BRAINLIEST PLEASE
Answer:
y = 5
Step-by-step explanation:
This is a multi-step equation, so you can solve for the variable 'y' by using a series of steps:
1. Combine like terms:
-4y - 3 = 5 - 3y + 6 -19 or -4y - 3 = -3y - 8
2. Isolate the variable using inverse (opposite operations):
Add 8 to both sides: -4y - 3 + 8 = -3y - 8 + 8 or -4y + 5 = -3y
Add -4y to both sides: -4y + 5 + 4y = -3y + 4y
3. Solve for 'y'
5 = y
