Question

(-2,6+х)-(х+0,6); -(3,5+m -8)+(7,15+m)​

Answer 1

(-2,6+x)-(x+0,6)
-2,6+x-x-0,6
-3,2
-16/5
-3 1/5


-(3,5+m-8)+(7,15+m)
-(-4,5+m)+7,15+m
4,5-m+7,15+m
11,65
233/20
11 13/20

Answer 2

It looks like you're asking me to simplify the given expressions. Let's solve each expression step by step:

1. (-2,6 + х) - (х + 0,6)

   Distribute the negative sign to both terms inside the parentheses:

   -2,6 - х - х - 0,6

   Combine like terms:

   -2,6 - 0,6 - 2х

   Now the expression is simplified:

   -3,2 - 2х

2. -(3,5 + m - 8) + (7,15 + m)

   First, simplify each set of parentheses:

   -(3,5 + m - 8) = -(4,5 + m) (7,15 + m) = 7,15 + m

   Now, distribute the negative sign:

   -4,5 - m + 7,15 + m

   Combine like terms (m and -m cancel out):

   -4,5 + 7,15

   Now the expression is simplified:

   2,65

So, the simplified expressions are:

1. -3,2 - 2х
2. 2,65
