Answer 2

To simplify the expression -7(x-5)-10-(3x+4), we can apply the distributive property and combine like terms.

First, let's simplify the expression inside the parentheses: -7(x-5) becomes -7x + 35. -(3x+4) becomes -3x - 4.

Now, let's rewrite the original expression with the simplified forms: -7x + 35 - 10 - (3x + 4).

Next, let's remove the parentheses: -7x + 35 - 10 - 3x - 4.

Now, let's combine like terms: (-7x - 3x) + (35 - 10 - 4).

Combining the x terms, we get: -10x + (35 - 10 - 4).

Simplifying the constant terms inside the parentheses: -10x + (21).

Therefore, the simplified expression is: -10x + 21.
