5d-2g=9;g

jimthompson5910 (jim_thompson5910):

The first step is to subtract 5d from both sides

jimthompson5910 (jim_thompson5910):

\[\Large 5d-2g=9\] \[\Large -2g=9-5d\]

jimthompson5910 (jim_thompson5910):

What's next?

OpenStudy (anonymous):

u just have to get the g alone

jimthompson5910 (jim_thompson5910):

i know, i'm asking what the next step is to do that

OpenStudy (anonymous):

umm idk

jimthompson5910 (jim_thompson5910):

you have -2 times g on the left side

jimthompson5910 (jim_thompson5910):

how do you undo that?

OpenStudy (anonymous):

u add 2 on both side i think

jimthompson5910 (jim_thompson5910):

what's the opposite of multiplication?

OpenStudy (anonymous):

divide

jimthompson5910 (jim_thompson5910):

both sides by what?

OpenStudy (anonymous):

umm 2

jimthompson5910 (jim_thompson5910):

that gives you this \[\Large -2g=9-5d\] \[\Large -g=\frac{9-5d}{2}\]

jimthompson5910 (jim_thompson5910):

Now flip the signs of both sides to get this \[\Large g=-\frac{9-5d}{2}\]

OpenStudy (anonymous):
