What is the full question?
One glass of milk has 11 carbs and one snack bar has 14 carbs.
Step-by-step explanation:
Let,
Glass of milk = x
Snack bar = y
According to given statement;
4x+2y=72 Eqn 1
2x+3y=64 Eqn 2
Multiplying Eqn 2 by 2

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 4

Putting y=14 in Eqn 1

Dividing both sides by 4

One glass of milk has 11 carbs and one snack bar has 14 carbs.
