# Vegetable stew

The recipe for vegetable stew is recommended to mix tomatoes, peppers, and onions in a ratio of 4: 3: 1. The cook has already prepared both onions and peppers, while the onions were five kg less than peppers. How many kilograms of tomatoes will he need according to this recipe?

r =  10 kg

### Step-by-step explanation:

c = p - 5
r = 4/3 • p
p = 3•c

c-p = -5
4p-3r = 0
3c-p = 0

c = 5/2 = 2.5
p = 15/2 = 7.5
r = 10
