To solve the equation

[ \frac{2x + 8}{x - 2} + 6 = 0, ]

we can start by isolating the fraction. First, subtract 6 from both sides:

[ \frac{2x + 8}{x - 2} = -6. ]

Next, we can eliminate the fraction by multiplying both sides by (x - 2), but we need to ensure that (x \neq 2) because that would make the denominator zero. Multiplying both sides gives:

[ 2x + 8 = -6(x - 2). ]

Expanding the right side:

[ 2x + 8 = -6x + 12. ]

Now, we collect all the (x) terms on one side and the constant terms on the other side. Adding (6x) to both sides results in:

[ 2x + 6x + 8 = 12, ]

or

[ 8x + 8 = 12. ]

Next, we subtract 8 from both sides:

[ 8x = 4. ]

Dividing both sides by 8, we find:

[ x = \frac{1}{2}. ]

Thus, the solution to the equation is

[ \boxed{\frac{1}{2}}. ]

To verify, we can substitute (x = \frac{1}{2}) back into the original equation:

[ \frac{2\left(\frac{1}{2}\right) + 8}{\frac{1}{2} - 2} + 6 = \frac{1 + 8}{\frac{1}{2} - 2} + 6 = \frac{9}{-\frac{3}{2}} + 6 = -6 + 6 = 0. ]

The equation holds true, confirming (x = \frac{1}{2}) is the correct solution.

2x+8/x-2+6=0
To solve the equation \[ \frac{2x + 8}{x - 2} + 6 = 0, \] we can start by isolating the fraction. First, subtract 6 from both sides: \[ \frac{2x + 8}{x - 2} = -6. \] Next, we can eliminate the fraction by multiplying both sides by \(x - 2\), but we need to ensure that \(x \neq 2\) because that would make the denominator zero. Multiplying both sides gives: \[ 2x + 8 = -6(x - 2). \] Expanding the right side: \[ 2x + 8 = -6x + 12. \] Now, we collect all the \(x\) terms on one side and the constant terms on the other side. Adding \(6x\) to both sides results in: \[ 2x + 6x + 8 = 12, \] or \[ 8x + 8 = 12. \] Next, we subtract 8 from both sides: \[ 8x = 4. \] Dividing both sides by 8, we find: \[ x = \frac{1}{2}. \] Thus, the solution to the equation is \[ \boxed{\frac{1}{2}}. \] To verify, we can substitute \(x = \frac{1}{2}\) back into the original equation: \[ \frac{2\left(\frac{1}{2}\right) + 8}{\frac{1}{2} - 2} + 6 = \frac{1 + 8}{\frac{1}{2} - 2} + 6 = \frac{9}{-\frac{3}{2}} + 6 = -6 + 6 = 0. \] The equation holds true, confirming \(x = \frac{1}{2}\) is the correct solution.
