To solve the equation \( 2x + 3 = 3x + 4 \), we can rearrange it to find the value of \( x \).
1. Start with the equation:
\[
2x + 3 = 3x + 4
\]
2. Subtract \( 2x \) from both sides:
\[
3 = x + 4
\]
3. Subtract \( 4 \) from both sides:
\[
3 - 4 = x
\]
\[
-1 = x
\]
Thus, the solution to the equation \( 2x + 3 = 3x + 4 \) is \( x = -1 \).
