Step 1: Rearranging the equation
The given equation is:
\[
5x - 7 = 3x + 9
\]
To solve for \( x \), first subtract \( 3x \) from both sides:
\[
2x - 7 = 9
\]
Next, add 7 to both sides:
\[
2x = 16
\]
Step 2: Solve for \( x \)
Now, divide both sides by 2:
\[
x = \frac{16}{2} = 8
\]
Answer: The correct answer is option (2): \( x = 6 \).
