Answer 2

Ответ:

12,5а+В+7-8а+5В-15= 4,5а+6В-8

Answer 3

To simplify the expression, we need to first remove the parentheses by distributing the negative sign:

12.5a + B + 7 - (8a - 5B + 15)

= 12.5a + B + 7 - 8a + 5B - 15

= (12.5a - 8a) + (B + 5B) + (7 - 15)

= 4.5a + 6B - 8

Therefore, the simplified expression is 4.5a + 6B - 8.
