Answer:

6,5g of protein

Step-by-step explanation:

80=4x + 9y

y=6 ( "6 grams of fat")

so: 80=4x+9.6

80-54= 4x

26/4=x

x(protein)= 6,5

Answer:

  6.5 grams

Step-by-step explanation:

To find the value of x that corresponds to the given value of y, put that y-value into the equation and solve for x.

  80 = 4x +9·6

  26 = 4x

  26/4 = x = 6.5

There are 6.5 grams of protein in the snack.
