Question

-8,3-(-х-8,3) и m-(n+m)

Answer 1

$-8,3-(-x-8,3) = -8,3+x+8,3=x$

$m-(n+m)=m-n-m=-n$

Answer 2

To simplify the expressions -8 + 3 - (-x - 8.3) and m - (n + m), let's break them down step by step:

1. -8 + 3 - (-x - 8.3): To simplify the expression, first, distribute the negative sign inside the parentheses: -8 + 3 + x + 8.3

   Now, combine the like terms: (-8 + 8.3) + 3 + x -0.3 + 3 + x

   Finally, add the constants: 2.7 + x

   So, the simplified expression is 2.7 + x.

2. m - (n + m): To simplify the expression, just distribute the negative sign inside the parentheses: m - n - m

   Now, combine the like terms (the 'm' terms cancel out): -n

   So, the simplified expression is -n.
