Answer:

he consumed 700 ml of cold drinks

Step-by-step explanation:

he consumed 2 bottles

1 bottle is equivalent to 350 ml

so let x is the total amount of cold water that he consumed and y for the amount of one bottle of cold drinks

y=350

x=2y

x=2(350)

x=700

so 700 ml is the total liters of cold drinks that the man consumed
