Solve it , determine the sum and product And thei rr ots

Let's work through each equation step-by-step to solve for \( x \), and then I will explain the sum and product of the roots.

### Equation 6:
\[
\frac{x - 1}{x + 3} = \frac{2}{x - 3}
\]
To solve this, we will cross-multiply:
\[
(x - 1)(x - 3) = 2(x + 3)
\]
Expanding both sides:
\[
(x^2 - 3x - x + 3) = 2x + 6
\]
Simplifying:
\[
x^2 - 4x + 3 = 2x + 6
\]
Now, move everything to one side of the equation:
\[
x^2 - 4x - 2x + 3 - 6 = 0
\]
\[
x^2 - 6x - 3 = 0
\]
Now we have a quadratic equation: 
\[
x^2 - 6x - 3 = 0
\]

We can solve this using the quadratic formula:
\[
x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(1)(-3)}}{2(1)}
\]
Simplifying:
\[
x = \frac{6 \pm \sqrt{36 + 12}}{2}
\]
\[
x = \frac{6 \pm \sqrt{48}}{2}
\]
\[
x = \frac{6 \pm 4\sqrt{3}}{2}
\]
\[
x = 3 \pm 2\sqrt{3}
\]

Thus, the solutions for \( x \) are:
\[
x = 3 + 2\sqrt{3}, \quad x = 3 - 2\sqrt{3}
\]

**Sum of the roots:**
The sum of the roots is \( 3 + 2\sqrt{3} + 3 - 2\sqrt{3} = 6 \).

**Product of the roots:**
The product of the roots is:
\[
(3 + 2\sqrt{3})(3 - 2\sqrt{3}) = 9 - (2\sqrt{3})^2 = 9 - 12 = -3
\]

### Equation 7:
\[
\frac{x - 4}{x} = \frac{x - 4}{5}
\]
Here, we can cancel \( x - 4 \) on both sides (assuming \( x \neq 4 \)):
\[
\frac{1}{x} = \frac{1}{5}
\]
Cross-multiplying:
\[
x = 5
\]

The solution for this equation is \( x = 5 \).
