What do you think it is, we'll go from there
OpenStudy (anonymous):
@Xander22 You might want to consider giving @Destinyrules1234 an explanation to why those are the correct answers. & the answer to your last question is q is 3, because -(3+14)=-3+-14
-3 +-14=-17
-(3+14) the negative sign in front of the two numbers makes both numbers negative so
-(3+14) is the same as -3+-14
OpenStudy (anonymous):
so is it 3?
OpenStudy (anonymous):
yes?
OpenStudy (anonymous):
Yes it is

What value of x makes the equation true?
–(9 + (–17)) = –9 + x
OpenStudy (anonymous):
Yes it is 3 which is C but do you understand why it is 3? Or do you want me to go over it again step by step ?
OpenStudy (anonymous):
i think it is 7 because it is opposite
OpenStudy (anonymous):
17*
OpenStudy (anonymous):
am i right?

hello????
OpenStudy (anonymous):
–(9 - 17) = –9 + x
–(-8) = –9 + x
8 = –9 + x
Add 9
8+9 = 9–9 + x
17 = x
Check it
–(9 + (–17)) = -(9-17) = -(-8) = +8
–9 + x ==> -9+17 = +8
