The Deep Dive
To solve the equation \( \frac{1}{x-2}-\frac{2}{x+3}=0 \), we first isolate one of the fractions. Start by moving the second fraction to the right side: \[ \frac{1}{x-2} = \frac{2}{x+3} \] Next, we'll cross-multiply to eliminate the fractions: \[ 1 \cdot (x + 3) = 2 \cdot (x - 2) \] This simplifies to: \[ x + 3 = 2x - 4 \] Now, rearranging the equation: \[ 3 + 4 = 2x - x \] This leads us to: \[ 7 = x \] So, the solution to the equation is \( x = 7 \). We should check if this value makes any original denominators equal to zero. The original denominators are \( x - 2 \) and \( x + 3 \): For \( x - 2 = 7 - 2 = 5 \) (not zero), For \( x + 3 = 7 + 3 = 10 \) (not zero). Thus, \( x = 7 \) is a valid solution. Final answer: \( x = 7 \).
