Answer 1

Как-то так, если я правильно понял))))

Answer 2

Solving the System of Equations

To solve the system of equations x + y = 7 and (x^2 - y^2)(x - y) = 175, we can use the following steps:

1. We can start by solving the first equation for one of the variables. Let's solve for x: x = 7 - y

2. Next, we can substitute the expression for x into the second equation: ((7 - y)^2 - y^2)(7 - y - y) = 175

3. Simplify the equation and solve for y.

Let's proceed with these steps to find the values of x and y.
