First, let's simplify the numbers within the parentheses:

7,86+4,183 = 12,043
0,314+0,207 = 0,521

Now, let's plug these values back into the original equation:

(12,043)-2,86 и 0,614-(0,521)

Now let's simplify further:

12,043 - 2,86 = 9,183
0,614 - 0,521 = 0,093

Therefore, the final answer is 9,183 и 0,093.
