Respuesta :

Answer:

The had 8 drinks

Step-by-step explanation:

Here, we want to calculate the number of drinks they had

Let the total number of drinks be x

And the number of drinks they had be y

From the first part, we have that;

x-3(y) = 3

x -3y = 3

x = 3 + 3y •••••••(i)

Secondly

x-2(y) = 11

x = 11 + 2y •••••(ii)

We equate the two x

11 + 2y = 3y + 3

3y-2y = 11-3

y = 8

So what this mean is that they had 8 drinks
