#### Problem Analysis We are given that there were an equal number of workers in two brigades. When 5 workers joined the first brigade and 4 workers left the second brigade, the first brigade ended up with 4 times as many workers as the second brigade. We need to determine the number of workers in each brigade. #### Solution Let's assume the initial number of workers in each brigade is **x**. According to the given information: - 5 workers joined the first brigade, so the number of workers in the first brigade became **x + 5**. - 4 workers left the second brigade, so the number of workers in the second brigade became **x - 4**. - The first brigade ended up with 4 times as many workers as the second brigade, so we can write the equation: **x + 5 = 4(x - 4)**. Now, let's solve this equation to find the value of **x**. #### Solving the Equation Expanding the equation: **x + 5 = 4x - 16** Simplifying the equation: **16 + 5 = 4x - x** **21 = 3x** Dividing both sides by 3: **x = 7** #### Answer Therefore, the initial number of workers in each brigade was **7**.
