Answer 2

To solve the given expression, let's simplify step by step:

5(-1,4x+3) - (1-2,5x) - 4(0,8x+3)

Step 1: Distribute the multiplication to each term inside the parentheses:

= 5 * -1,4x + 5 * 3 - (1 - 2,5x) - 4 * 0,8x - 4 * 3

= -7x + 15 - (1 - 2,5x) - 3,2x - 12

Step 2: Simplify within the parentheses:

= -7x + 15 - 1 + 2,5x - 3,2x - 12

= -7x + 15 - 1 - 3,2x + 2,5x - 12

Step 3: Combine like terms:

= (-7x - 3,2x + 2,5x) + (15 - 1 - 12)

= -7x - 3,2x + 2,5x + 2

= -7x - 0,7x + 2

= -7,7x + 2

So the simplified expression is -7,7x + 2.
