Step 1: Rearrange the equation
Given the equation:
\[
2x - 3 = 5x + 12
\]
To isolate \( x \), move all \( x \) terms to one side.
Subtract \( 2x \) from both sides:
\[
-3 = 3x + 12
\]
Step 2: Simplify the equation
Subtract 12 from both sides:
\[
-3 - 12 = 3x
\]
\[
-15 = 3x
\]
Step 3: Solve for \( x \)
Divide both sides by 3:
\[
x = \frac{-15}{3} = -5
\]
Answer:
Thus, \( x = -5 \). The correct answer is option (3).
