Problem Analysis

We are given the following information: - The combined weight of an apple, a pear, and a peach is 470 grams. - The combined weight of an apple and a pear is 330 grams. - The combined weight of a pear and a peach is 310 grams.

We need to find the weight of each fruit.

Solution

Let's assign variables to represent the weights of the apple, pear, and peach. We'll use the variables A, P, and C, respectively.

From the given information, we can set up the following equations:

1. A + P + C = 470 (equation 1) 2. A + P = 330 (equation 2) 3. P + C = 310 (equation 3)

To solve this system of equations, we can use substitution or elimination. Let's use substitution.

From equation 2, we can express A in terms of P: A = 330 - P.

Substituting this value of A into equations 1 and 3, we get:

(330 - P) + P + C = 470 (equation 1) P + C = 310 (equation 3)

Simplifying equation 1, we have:

330 + C = 470 C = 470 - 330 C = 140

Substituting the value of C into equation 3, we get:

P + 140 = 310 P = 310 - 140 P = 170

Finally, substituting the values of P and C into equation 2, we can find the value of A:

A + 170 = 330 A = 330 - 170 A = 160

Therefore, the weight of the apple is 160 grams, the weight of the pear is 170 grams, and the weight of the peach is 140 grams.

Answer

The weight of each fruit is as follows: - Apple: 160 grams - Pear: 170 grams - Peach: 140 grams
