\( x = 12.5 \)

Solución

Certainly! Let's solve the equation step by step. **Given Equation:** \[ 8.6 = x - 3.9 \] **Step 1:** To find the value of \( x \), we need to isolate it on one side of the equation. **Step 2:** Add \( 3.9 \) to both sides of the equation to eliminate the \(-3.9\) on the right side. \[ 8.6 + 3.9 = x - 3.9 + 3.9 \] **Step 3:** Simplify both sides. \[ 12.5 = x \] **Final Answer:** \[ x = 12.5 \] So, the value of \( x \) is **12.5**.

To solve the equation \( 8.6 = x - 3.9 \), you’ll want to isolate \( x \). Start by adding \( 3.9 \) to both sides of the equation. So, \( 8.6 + 3.9 = x \). This will give you the value of \( x \) as \( 12.5 \). Voila! One common mistake is forgetting to perform the same operation on both sides of the equation. For example, if you subtract instead of adding that \( 3.9 \), your solution will be off. Always double-check your arithmetic to ensure you’re adding or subtracting correctly!
