x-2(x+5)

To simplify the expression \( x - 2(x + 5) \), follow these steps:

1. Distribute the \(-2\) across the terms in the parentheses: \[ -2(x + 5) = -2x - 10 \]

2. Rewrite the expression with the distributed terms: \[ x - 2x - 10 \]

3. Combine like terms: \[ (1x - 2x) - 10 = -1x - 10 \]

So, the simplified expression is: \[ -x - 10 \]

Alternatively, you could write it as: \[ -(x + 10) \]

Both forms are correct!
