One shake and two beef burritos provide 3400 calories. Two shakes and one beef burrito provide 2750 calories. Find the caloric content of each item

Answer 1

Let's say shake is S and Burrito is B

S + 2B = 3400

2S + B = 2750

S = 700 calories

B = 850 calories

Answer 2

s + 2b = 3400

2s + b = 2750

s + 2b = 3400

-4s - 2b = -5500

-3s = -2100

s = 700 calories

700 + 2b = 3400

2b = 1700

b = 850 calories
