Раскроем скобки и получим 3а+5в+9а-7в-5а+11в = 3а+9а-5а+5в-7в+11в = 7а+9в

Answer 2

17а+9в .. .. . ....... ......

Answer 3

To simplify the expression, you need to combine like terms. Like terms are terms that have the same variables raised to the same powers.

The given expression is:

(3a + 5в) + (9a - 7в) + (5a + 11в)

To simplify, group the like terms together:

(3a + 9a + 5a) + (5в - 7в + 11в)

Now, combine the like terms:

(3a + 9a + 5a) = 17a (5в - 7в + 11в) = 9в

The simplified expression is:

17a + 9в
