Question

6*(5a+3)-(7+a)-2*(4-3a)=

Answer 1

6*(5a+3)-(7+a)-2*(4-3a)=30a+18-7-a-8+6a=35a+3.

Объяснение:
Сначала мы:
I.30a-a+6a= 29a+6a=35a
II.18-7-8=11-8=3

Answer 2

Let's simplify the given expression step by step:

$6(5a+3) - (7+a) - 2(4-3a)$

First, distribute the 6 in the first term and the -2 in the third term:

$= 30a + 18 - (7 + a) - 8 + 6a$

Next, simplify within the parentheses:

$= 30a + 18 - 7 - a - 8 + 6a$

Combine like terms:

$= (30a - a + 6a) + (18 - 7 - 8)$

$= 35a + 3$

So, the simplified expression is $35a + 3$.
