1+(0,5x-3)-(1,5x-4)

To simplify the expression \(1 + (0.5x - 3) - (1.5x - 4)\), let's proceed step by step:

1. Distribute the negative sign in front of the second parentheses: \[ 1 + (0.5x - 3) - (1.5x - 4) = 1 + 0.5x - 3 - 1.5x + 4 \]

2. Combine like terms:

   • Combine the constant terms: \(1 - 3 + 4 = 2\)
   • Combine the terms with \(x\): \(0.5x - 1.5x = -1x\) or \(-x\)

3. Write the simplified expression: \[ -x + 2 \]

Thus, the simplified expression is: \[ -x + 2 \]
