-3(x + 3)- 2(x + 4)=

-3x + 9 - 2x + 8=
-3x - 2x + 9 + 8=
answer x + 17

is this correct

better form would be to place the equal sign in front of each new line

You also have errors

-3(x + 3)- 2(x + 4)
= -3x - 9 - 2x - 8
= -3x - 2x - 9 - 8
= -5x - 17

You forgot the negative numbers.

-3(x + 3)- 2(x + 4)=

-3x - 9 - 2x - 8 = -5x - 17

so -3 x 3 made -9. how did the 2 become negative, I thought it was a subtraction sign?

Yes, that is correct. When simplifying the expression -3(x + 3) - 2(x + 4), you need to distribute the -3 and -2 to the terms inside the parentheses. This results in -3x - 9 - 2x - 8.

Next, you combine like terms by adding or subtracting the terms with the same variable. In this case, you have -3x, -2x, -9, and -8. Combining -3x and -2x gives -5x, and combining -9 and -8 gives -17.

So the simplified expression is -5x - 17.

The answer you provided, x + 17, is not correct.
