Answer:
step 4
Step-by-step explanation:
-6x=57
-6x÷-6=57÷-6
x=-9.5
1 litre=1000mL so we know that 4x1000= 4000mL
Since she poured 160 mL for TWO friends
160x2=320
She then says that another friend has 215 mL of lemonade.
So that means
4000-320-215= 3465 mL
Therefore Lydia has 3465mL or 3.465L of lemonade left
