Ameal of a chicken sandwich and some pasta salad had 120 grams of carbohydrates. the pasta salad had 30 grams more than twice the grams of carbohydrates in the chicken sandwich. find the number of grams of carbohydrates for both.

C + p = 120c = chicken sandwich carbs, p = pasta salad carbs
p = 2c + 30

c + (2c + 30) = 120
3c + 30 = 120
3c = 120 - 30
3c = 90
c = 90/3
c = 30 grams <=== carbs in the chicken sandwich

p = 2c + 30
p = 2(30) + 30
p = 60 + 30
p = 90 grams <=== carbs in the pasta salad
