Answer 2

To solve the equation 4x - 4y/x + y + 3x + 3y/x - y = 13, we can follow these steps:

1. Simplify the equation: Combine like terms in the numerator and denominator separately. Numerator: (4x - 4y) + (3x + 3y) = 7x - y Denominator: (x + y) + (x - y) = 2x

   The equation becomes: (7x - y)/(2x) = 13

2. Multiply both sides of the equation by 2x to eliminate the denominator: 2x * (7x - y)/(2x) = 13 * 2x

   Simplifying: 7x - y = 26x

3. Move all terms involving x to one side and terms involving y to the other side: 7x - 26x = y

   Simplifying: -19x = y

4. Rewrite the equation in terms of one variable: y = -19x

Now we have a relationship between x and y, where y is equal to -19 times x. This equation represents a straight line in the xy-plane with a slope of -19.
