Answer

\( x = -10 \)

Solution

Solve the equation \( \frac{x+2}{x-6}=\frac{1}{2} \). Solve the equation by following steps: - step0: Solve for \(x\): \(\frac{x+2}{x-6}=\frac{1}{2}\) - step1: Find the domain: \(\frac{x+2}{x-6}=\frac{1}{2},x\neq 6\) - step2: Cross multiply: \(\left(x+2\right)\times 2=x-6\) - step3: Simplify the equation: \(2\left(x+2\right)=x-6\) - step4: Expand the expression: \(2x+4=x-6\) - step5: Move the expression to the left side: \(2x-x=-6-4\) - step6: Add and subtract: \(x=-6-4\) - step7: Add and subtract: \(x=-10\) - step8: Check if the solution is in the defined range: \(x=-10,x\neq 6\) - step9: Find the intersection: \(x=-10\) The solution to the equation \(\frac{x+2}{x-6}=\frac{1}{2}\) is \(x=-10\).

Bonus Knowledge

To solve the equation \(\frac{x+2}{x-6}=\frac{1}{2}\), you can start by cross-multiplying to eliminate the fractions. This means you multiply both sides by \(2(x - 6)\), leading to \(2(x + 2) = 1(x - 6)\). Simplifying this gives \(2x + 4 = x - 6\). Now, rearrange by subtracting \(x\) from both sides to get \(2x - x + 4 = -6\) or \(x + 4 = -6\). Finally, subtract 4 from both sides to find \(x = -10\). Just like in a balancing act, when you cross-multiply and rearrange, you have to keep everything in check! A common mistake is forgetting to apply the same operation on both sides of the equation, leading to incorrect solutions or messy equations. So always double-check your steps!
