2*2-(х-3+7)

To simplify the expression \( 2*2 - (x - 3 + 7) \), we can follow these steps:

1. Calculate \( 2*2 \): \[ 2 * 2 = 4 \]

2. Simplify the expression inside the parentheses \( (x - 3 + 7) \): \[ -3 + 7 = 4 \] So, \( (x - 3 + 7) = (x + 4) \).

3. Substitute back into the expression: \[ 4 - (x + 4) \]

4. Distribute the negative sign: \[ 4 - x - 4 \]

5. Combine like terms: \[ 4 - 4 - x = -x \]

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