Solution 1

To solve this problem, we need to use the concept of ratios and proportions. Here are the steps:

  1. We are given that (A - x): (A - y): (A - z) = 1: 7: 4. This means that A - x, A - y, and A - z are in the ratio 1:7:4.

  2. We are also given that 2A = x + y + z.

  3. We can express x, y, and z in t Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
