4) -(а+5)+2а-4

-а-5+2а-4

а-5-4

а-9

Answer 2

It looks like you've provided an expression that involves several variables and arithmetic operations. Let's simplify the expression step by step:

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

Let's distribute the constants and variables within parentheses first:

2a - 6 + 6x - 6 - 3(2) - 3x + 7 - 3(x) + 15 + 6x - a - 5 + 2a - 4

Now, let's simplify the terms involving constants:

2a + 6x - 6 - 6 - 6x + 7 - 3x + 15 + 6x - a - 5 + 2a - 4

Combining like terms:

(2a + 2a) + (6x - 6x - 3x + 6x) - (a) + (7 + 15 - 5 - 4) - (6 - 6)

Simplifying further:

4a + 3x + 13

So, the simplified expression is 4a + 3x + 13.
