Answer 2

To find the values of x and y in the equation 7xy:xy7=378, let's first understand the structure of the equation.

7xy:xy7=378

Here, 7xy represents a three-digit number with digits 7, x, and y (in that order). Similarly, xy7 represents a three-digit number with digits x, y, and 7 (in that order). The colon (:) between them represents concatenation, which means we combine the two three-digit numbers to form a six-digit number.

Now, we can set up the equation step-by-step:

1. Combine the two three-digit numbers: 7xyxy7 = 700,000 + 10,000x + 1000y + 100x + 10y + 7

2. Simplify the equation: 7xyxy7 = 700,000 + 100,100x + 1010y + 7

3. Set the equation equal to 378: 700,000 + 100,100x + 1010y + 7 = 378

4. Move constants to one side and variables to the other side: 100,100x + 1010y = 378 - 700,000 + 7 100,100x + 1010y = -699,615

Now, it's important to note that we have two variables (x and y) but only one equation. So, there are infinitely many solutions for x and y that satisfy this equation.

Without more information or constraints, we cannot uniquely determine the values of x and y. We would need additional equations or information to narrow down the possible solutions.
