To subtract \(3x\) from both sides of the equation \(3x + 5 = 3x - 4\), you can follow these steps:
Start with the original equation:
\[ 3x + 5 = 3x - 4 \]
Now subtract \(3x\) from both sides:
\[ (3x + 5) - 3x = (3x - 4) - 3x \]
This simplifies to:
\[ 5 = -4 \]
So the final rewritten equation is:
\[ 5 = -4 \]
This indicates that there is no solution since this statement is false.
