well -14
OpenStudy (anonymous):
oh i see
OpenStudy (destinymasha):

OpenStudy (destinymasha):
-9 - 8 = -17 , -17 divided by 2 = 8.5
OpenStudy (destinymasha):
how about 2 ?
2 - 8 = -6 , negative 6 divided by 2 = -3 !!!

I believe its A
OpenStudy (destinymasha):
4 x -2 = -8 , -8 + 2 = -6. So x has to be equal to or less than -6
OpenStudy (destinymasha):
-2 i meant
OpenStudy (the_fizicx99):
Are you using the options to find the answer? @Destinymasha
OpenStudy (destinymasha):

OpenStudy (the_fizicx99):
4x + 2 ≥ -6
-2 -2
4x ≥ -8
/4 /4
x ≥ -2
OpenStudy (destinymasha):
we are trying to find x
OpenStudy (anonymous):
yep
OpenStudy (the_fizicx99):
\[3x -6 = -2x + 9\]
\[3x = -2x + 15\]
\[5x = 15\]
\[x = 3\]
OpenStudy (destinymasha):
Its C. 3

What is the solution to the equation?
3x – 6 = –2x + 9
OpenStudy (the_fizicx99):
What if x were 9875 ? you would check each option til you got to 9875?!? Lol, smh
OpenStudy (the_fizicx99):
@Waraiders I just gave you a step by step explanation above.
OpenStudy (destinymasha):
I just did that.
OpenStudy (destinymasha):
exchange every x for every number there and see which ones match

i mean
What is the solution to the equation?
t(9 – 1) = 5 • 9 – 5 • 1
OpenStudy (destinymasha):
I am sure @tHe_FiZiCx99 would like to help you.
OpenStudy (anonymous):
lol
OpenStudy (the_fizicx99):
No thats not how you solve!!!
t(9 – 1) = 5 • 9 – 5 • 1
|dw:1389747156689:dw|
9t -1t = 45 - 5
8t = 40
t = 5
