Answer 2

To simplify the expression -(2,7a-1,46b)-(0,5b+2,3a)+(2,16+3,5a), we'll perform the operations step by step:

Step 1: Distribute the negative sign to both terms within the first parentheses: -(2,7a - 1,46b) = -2,7a + 1,46b

Step 2: Distribute the negative sign to both terms within the second parentheses: -(0,5b + 2,3a) = -0,5b - 2,3a

Step 3: Add the terms from Step 1 and Step 2 to the third parentheses: (2,16 + 3,5a) = 2,16 + 3,5a

Step 4: Now combine all the simplified terms: -2,7a + 1,46b - 0,5b - 2,3a + 2,16 + 3,5a

Step 5: Combine the like terms (terms with the same variables): (-2,7a - 2,3a + 3,5a) + (1,46b - 0,5b) + 2,16

Step 6: Simplify the like terms: -1,5a + 0,96b + 2,16

So, the simplified expression is -1,5a + 0,96b + 2,16.
