OpenStudy (michele_laino):

ok! Now write your equation

OpenStudy (michele_laino):

please without using the editor

OpenStudy (nuccioreggie):

\[\frac{ -3 }{ 2 }×-9=27\]

OpenStudy (michele_laino):

is your equation, like this? \[ \Large - \frac{3}{2}x - 9 = 27\]

OpenStudy (nuccioreggie):

Yes

OpenStudy (michele_laino):

here we ahve to add 9 to both sides, so we can write: \[\Large - \frac{3}{2}x - 9 + 9 = 27 + 9\] please simplify

OpenStudy (nuccioreggie):

Its -12?

OpenStudy (michele_laino):

we have: \[\Large - \frac{3}{2}x = 36\]

OpenStudy (michele_laino):

now I multiply both sides by -2/3, so I can write: \[\Large x = 36 \times \left( { - \frac{2}{3}} \right) = ...?\] what is x?

OpenStudy (nuccioreggie):

11

OpenStudy (michele_laino):

what is 36*(-2)=...?

OpenStudy (nuccioreggie):

-72

OpenStudy (michele_laino):

ok! and what is -72/3=...?

OpenStudy (nuccioreggie):

-24
