a-3458=145340

To solve the equation \( a - 3458 = 145340 \), you need to isolate \( a \). You can do this by adding 3458 to both sides of the equation:

\[ a - 3458 + 3458 = 145340 + 3458 \]

This simplifies to:

\[ a = 145340 + 3458 \]

Now, calculate the right side:

\[ 145340 + 3458 = 148798 \]

Therefore, the value of \( a \) is:

\[ \boxed{148798} \]
