✔ 最佳答案
Let x calories and y calories be the caloric content of shake and burrito respectively.x + 2y = 3760 ...... [1]
2x + y = 3470 ...... [2]
[1] + [2] :
3x + 3y = 7230
x + y = 2410 ...... [3]
[1] - [3] :
y = 1350
[2] - [3] :
x = 1060
Caloric content of each item :
Shake : 1060 calories
Burrito : 1350 calories

s + 2b = 3760
2s + b = 3470 → b = 3470-2s
s + 2(3470-2s) = 3760
-3s = 3760 - 6940 = -3180
shake = 3180/3 = 1060 calories
burrito = 3470-2120 = 1350 calories
2s + b = 3470 → b = 3470-2s
s + 2(3470-2s) = 3760
-3s = 3760 - 6940 = -3180
shake = 3180/3 = 1060 calories
burrito = 3470-2120 = 1350 calories
