Answer 1

Пошаговое объяснение:

-(-5,2-3,1с)-(2,4с-6,4)=

= 5,2+3,1с-2,4с+6,4=11,6+0,7с

Answer 2

-(-5.2-3.1c)-(2.4c-6.4)

5.2+3.1c-(2.4c-6.4)

5.2+3.1c-(12/5c-6.4)

5.2+3.1c-(12/5c-32/5)

26/5+3.1c-(12/5c-32/5)

26/5+31/10c-(12/5c-32/5)

26/5+31/10c-4/5*(3c-8)

1/10*(52+31c)-4/5*(3c-8)

1/10*(52+31c-8(3c-8))

1/10*(52+31-24c+64)

1/10*(116+31c-24c)

1/10*(116+7c)

Answer 3

To simplify the expression $-(-5,2-3,1c)-(2,4c-6,4)$, you need to distribute the negative sign and then combine like terms. Let's break down the steps:

1. Distribute the negative sign in front of the parentheses:

$-(-5,2-3,1c)-(2,4c-6,4)$

This becomes:

$(5,2-3,1c)-(2,4c-6,4)$

2. Now distribute the subtraction inside the parentheses:

$(5,2-3,1c)-(2,4c-6,4)$

This becomes:

$(5,2-3,1c)-2-(4c-6,4)$

3. Distribute subtraction inside the parentheses:

$(5,2-3,1c)-2-(4c-6,4)$

This becomes:

$(5-3,1c)-2-(4c+6,4)$

4. Combine like terms:

$(1,1c)-2-(4c+6,4)$

Now, the expression $-(-5,2-3,1c)-(2,4c-6,4)$ simplifies to $(1,1c)-2-(4c+6,4)$.
