combine like terms

To combine like terms in the expression \(2x - 3x + 7 - 10 + 2x\), we can group the \(x\) terms and the constant terms separately.

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

2. Combine the constant terms:
\[
7 - 10 = -3
\]

Now, putting it all together, we have:
\[
x - 3
\]

So, the combined expression is:
\[
\boxed{x - 3}
\]
