I need help solving college algebra word problem

A one-cup serving of spaghetti with meatballs contains 260 calories and 32 grams of carbohydrates. A one-cup serving of chopped iceberg lettuce contains 5 calories and 1 gram
of carbohydrates. Determine how many servings of each would be required to obtain 480 calories and 60 grams
of carbohydrates

How may serving(s) of spaghetti would be required?
(Round to the nearest tenth.)

How many serving(s) of iceberg lettuce would be required?
(Round to the nearest tenth.)

260S+5L=480

32S+1L=60

260S+5L=480
5(32S+1L=60)

260S+5L=480
160S+5L=300

100S=180

S=180/100=1.8 serving of spaghetti
L=2.4 serving Lettuce
