\[\frac{-8((12-6)+3)+4}{(9-2(2+3))}\]Solve for the inner most parenthesis first.

OpenStudy (jhannybean):

\[\frac{-8(\color{red}{(12-6)}+3)+4}{(9-2\color{red}{(2+3)})}\]

OpenStudy (winsteria):

12-6 =6 2+3 = 5

OpenStudy (jhannybean):

Alright. \[\frac{-8(6+3)+4}{(9-2(5))}\]

OpenStudy (jhannybean):

Now solve :\[\frac{-8\color{red}{(6+3)}+4}{(9-\color{red}{2(5)})}\]

OpenStudy (winsteria):

6+3 = 9 2 x 5 = 10

OpenStudy (jhannybean):

\[\frac{\color{red}{-8(9)}+4}{\color{red}{(9-10)}}\]

OpenStudy (winsteria):

-8 x 9 = -72 9 - 10 = -1

OpenStudy (jhannybean):

\[\frac{\color{red}{-72+4}}{-1}\]

OpenStudy (winsteria):

-72 + 4 = -68

OpenStudy (jhannybean):

\[\frac{-68}{-1}\]

OpenStudy (winsteria):

but it can't be the answer as a fraction...?

OpenStudy (jhannybean):

What is 68/1

OpenStudy (winsteria):

68

OpenStudy (jhannybean):

There you go.
