Question

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

Answer 1

Відповідь:  $-7,7x+2$

Покрокове пояснення:

$5(-1,4x+3)-(1-2,5x)-4(0,8x+3)=-7x+15-1+2,5x-3,2x-12=-7,7x+2$

Answer 2

To simplify the expression 5(-1.4x+3) - (1-2.5x) - 4(0.8x+3), you'll need to distribute the constants and perform the operations step by step. Here's how you can do it:

1. Distribute the constants: 5 * (-1.4x) + 5 * 3 - (1 - 2.5x) - 4 * (0.8x) - 4 * 3

2. Perform the multiplications: -7x + 15 - 1 + 2.5x - 3.2x - 12

3. Combine like terms: (-7x + 2.5x - 3.2x) + (15 - 1 - 12)

4. Simplify the terms with x: -7x + 2.5x - 3.2x = -7.7x

5. Simplify the constants: 15 - 1 - 12 = 2

6. Combine the simplified terms: -7.7x + 2

So, the simplified expression is -7.7x + 2.
