Пошаговое объяснение:

-(2,7+x-7,8)-(6,2-x)=​ -2,7 - х + 7,8 - 6,2 + х = -1.1

Answer 3

To simplify the expression -(2,7+x-7,8)-(6,2-x), follow these steps:

Step 1: Remove the parentheses and distribute the negative sign to both terms within the first set of parentheses: -(2,7+x-7,8) = -2 - (x-7.8) = -2 - x + 7.8

Step 2: Remove the parentheses and distribute the negative sign to both terms within the second set of parentheses: -(6,2-x) = -6.2 + x

Now, the expression becomes:

-2 - x + 7.8 - (-6.2 + x)

Step 3: Simplify further by combining like terms:

-2 - x + 7.8 + 6.2 - x

Step 4: Combine the constant terms and the x terms separately:

(7.8 + 6.2) + (-2 - x - x) = 14 - 2x

The simplified expression is 14 - 2x.
