1)2(-3a+9в-2c)=...... 2)-(-2+3a)-3в)=.... 3)7(-в+10p-3a)=.,.. 4)-2(9x-3x+y)=... 5)-(-2a+В+3с)=... 6)-(-5-а-8в)=..... 7)-(-3(в-2с-3а))=....

Answer 1

Ответ:

1) -6а+18в-4с

2)-(6в-9ав)=-6в+9ав

3)-7в+70р-21а

4)-18х+6х-2у

5)2а-в-3с

6)5+а+8в

7)-(-3в+6с+9а)=3в-6с-9а

Answer 2

Let's simplify the given expressions:

1. $2(-3a + 9b - 2c) = -6a + 18b - 4c$

2. $-(-2 + 3a) - 3b = 2 - 3a - 3b$

3. $7(-b + 10p - 3a) = -7b + 70p - 21a$

4. $-2(9x - 3x + y) = -2(6x + y) = -12x - 2y$

5. $-(-2a + b + 3c) = 2a - b - 3c$

6. $-(-5 - a - 8b) = 5 + a + 8b$

7. $-(-3(b - 2c - 3a)) = -3(-b + 2c + 3a) = 3b - 6c - 9a$
