    Answer:

    Glass of milk=15 carbs

    One snack bar=11 carbs

    Step-by-step explanation:

    ×2 2m+3s=63…………………..1

    ×1 4m+2s=82…………..2

    4m+6s=126

    4m+2s=82

    Cancel out the 4ms

    6s=126

    2s=82

    minus top and bottom equations and remain with

    4s= 44

    s=44/4

    s=11 ∴ one snack bar is 11 carbs

    subs s=11 into equation 1

    2m+3s=63

    2m+3(11)=63

    2m+33=63

    2m=63-33

    2m=30

    m=30/2

    m=15  ∴one glass of milk is 15 carbs
