To solve for \( x \) in the equation \(-x + 171 = 106\), we need to isolate \( x \). We can do this by first subtracting 171 from both sides of the equation and then multiplying both sides by -1 to solve for \( x \).
Step 1: Understand the Problem
We need to solve for \( x \) in the equation:
\[
-x + 171 = 106
\]
Step 2: Isolate the Variable
To isolate \( x \), we first need to get rid of the constant term on the left side. We do this by subtracting 171 from both sides of the equation:
\[
-x + 171 - 171 = 106 - 171
\]
This simplifies to:
\[
-x = 106 - 171
\]
Step 3: Simplify the Right Side
Next, we simplify the right side of the equation:
\[
106 - 171 = -65
\]
So, the equation becomes:
\[
-x = -65
\]
Step 4: Solve for \( x \)
To solve for \( x \), we need to get rid of the negative sign in front of \( x \). We do this by multiplying both sides of the equation by -1:
\[
-x \cdot (-1) = -65 \cdot (-1)
\]
This simplifies to:
\[
x = 65
\]
