To solve the equation \( 2x + 3 = 3x + 4 \), follow these steps:
- Subtract \( 2x \) from both sides:
\[ 3 = 3x - 2x + 4 \]
This simplifies to:
\[ 3 = x + 4 \]
- Next, subtract \( 4 \) from both sides:
\[ 3 - 4 = x \]
This simplifies to:
\[ -1 = x \]
Therefore, the solution to the equation \( 2x + 3 = 3x + 4 \) is:
\[ x = -1 \]
