Which expression is equivalent to x+4+2x–1?

Answer 1

To simplify the expression \( x + 4 + 2x - 1 \), you can combine like terms:

1. Combine the \( x \) terms:
\[
x + 2x = 3x
\]

2. Combine the constant terms:
\[
4 - 1 = 3
\]

Putting it all together:
\[
x + 4 + 2x - 1 = 3x + 3
\]

So, the equivalent expression is \( 3x + 3 \).
