1(0,5х-6)-(1,5-4)

Let's simplify the expression step by step.

The expression you provided is:

\[ 1(0.5x - 6) - (1.5 - 4) \]

1. Distribute the 1 in the first part of the expression: \[ 0.5x - 6 \]

2. Simplify the second part of the expression: \[ 1.5 - 4 = -2.5 \]

3. Now substitute these back into the expression: \[ 0.5x - 6 - (-2.5) \]

4. When you subtract a negative, it becomes addition: \[ 0.5x - 6 + 2.5 \]

5. Now combine the constant terms: \[ 0.5x - 3.5 \]

So the simplified expression is:

\[ 0.5x - 3.5 \]
