Сперва открываем скобки как следует:

-3x-1+(-7x)+9

Answer 3

To simplify the expression -(3x + 1) + (-7x + 9), we can distribute the negative sign to each term inside the parentheses. This means we need to change the sign of each term.

-(3x + 1) + (-7x + 9) can be rewritten as -3x - 1 + (-7x + 9).

Now, we can combine like terms. The like terms are the ones with the same variable (x).

-3x - 7x gives us -10x, and -1 + 9 gives us 8.

Therefore, -(3x + 1) + (-7x + 9) simplifies to -10x + 8.
