@Destinymasha

OpenStudy (destinymasha):

x -8 divided by 2 = -3

OpenStudy (destinymasha):

lets try each one

OpenStudy (destinymasha):

14 - 8 = 6, 6 divided by 2 = 3

OpenStudy (destinymasha):

well -14

OpenStudy (anonymous):

oh i see

OpenStudy (destinymasha):

how about -9 ?

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 !!!

OpenStudy (destinymasha):

The answer is C [2]

OpenStudy (anonymous):

I get it thanks

OpenStudy (destinymasha):

Your welcome, as always :}

OpenStudy (anonymous):

new problem

OpenStudy (destinymasha):

4 times what +2 is equal to or greater than -6.

OpenStudy (destinymasha):

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):

yea

OpenStudy (destinymasha):

I said A

OpenStudy (the_fizicx99):

You can't use the option..

OpenStudy (destinymasha):

what, what do you mean?

OpenStudy (anonymous):

thanks i got 3 more questions

OpenStudy (anonymous):

What option

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

OpenStudy (destinymasha):

SUBSTITUTE 3 FOR EACH X IN THE EQUATION

OpenStudy (the_fizicx99):

@Destinymasha Please refrain from giving out answers

OpenStudy (destinymasha):

im not.

OpenStudy (anonymous):

its cool

OpenStudy (the_fizicx99):

You just did

OpenStudy (destinymasha):

3[3] - 6 = 3 -2[3] +9 = 3

OpenStudy (destinymasha):

i did, but i am not

OpenStudy (the_fizicx99):

It's right yes, but stop giving out answers.

OpenStudy (destinymasha):

did you not see me guide him step by step before?

OpenStudy (the_fizicx99):

No, you used the options. lol..

OpenStudy (destinymasha):

?

OpenStudy (the_fizicx99):

How would you solve this if you didn't have the options..?

OpenStudy (destinymasha):

1]estimate and check or go from 1 to 100. :}

OpenStudy (the_fizicx99):

No. Just NO.

OpenStudy (destinymasha):

huh?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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 (destinymasha):

So i dont have to type it all - http://www.geteasysolution.com/t(9-1)=5*9-5*1

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
