What does 9(x+1) - 5(x+1)?

Question

It its combine like terms with parentheses. PLEASE HELP ME!!!

Answer 1

9(x+1) - 5(x+1)=

9x+9-5x-5=

4x+4=answer

Answer 2

I think it would be good for you to learn HOW to solve this in general.

Always MULTIPLY first!

for this problem:
1) first mltiply the terms in the paretheses by the 9 and the 5:
(9x +9) -(5x+5)

2) the "-" (minus) sign in front of the second paranthesis will change the signs of the terms, when you get rid of the paranthesis:
(9X+9) -5X-5

3) we have no minus sign in front of the first paranthesis, right? So nothing changes for those terms:
9x+9-5x-5

4) so answer is 4x+4

Answer 3

9(x+1)-5(x+1)

First, you would distribute the 9 to the x and 1.

9x+9-5(x+1)

Now, you would distribute the -5 (remember, subtracting a number is basically adding a negative number) to the x and the 1.

9x+9-5x-5

Now, you would combine like terms.

4x-4

Answer 4

9x + 9 - 5x - 5
= 4x + 4
Also known as 4 ( x + 1 ).
But, 4x + 4 is simplified enough.

But, if you're solving for x or whatever,
9 (x + 1) - 5 (x+1)
9x + 9 - 5x -5 = 0
4x + 4 = 0
4x = -4
x = -1

Answer 5

9(x+1)-5(x+1)= 9x+9-5x-5=4+4x

Answer 6

9x+9-5x-5=4x-4

Answer 7

9(x+1)-5(x+1)
9x+9+-5x+-5
4x+4

Answer 8

9x+9-5x-5=0
4x+4=0
x=-1

Answer 9

Most of these answers given are correct, but also remember that this is not an equation. It's just an expression since there's no = sign.
