Answer 2

To simplify the expression -(5,7m - 6,7) - (7,9 - 3,6m), follow these steps:

Step 1: Distribute the negative sign to both terms inside the first parentheses: -(5,7m - 6,7) = -5,7m + 6,7

Step 2: Distribute the negative sign to both terms inside the second parentheses: -(7,9 - 3,6m) = -7,9 + 3,6m

Now the expression becomes: (-5,7m + 6,7) - (7,9 - 3,6m)

Step 3: Remove the parentheses and combine like terms: -5,7m + 6,7 - 7,9 + 3,6m

Step 4: Combine the "m" terms and the constant terms separately: (-5,7m + 3,6m) + (6,7 - 7,9)

Step 5: Combine the "m" terms and the constant terms: (-2,1m) + (-1,2)

Finally, the simplified expression is: -2,1m - 1,2
