13+w/7=-18

OpenStudy (stefrheart):

Are you solving for w?

OpenStudy (goldphenoix):

Does it literally state that in the paper or is it either A: \[\large \large 13+\frac{ w }{ 7 }= -18\] or B: \[\large \large \frac{ 13+w }{ 7 } = -18\] Or C: none of the above / not sure

OpenStudy (anonymous):

Yeah its B

OpenStudy (stefrheart):

First you need to multiply the 7 on both sides

OpenStudy (anonymous):

So 7x13 and w?

OpenStudy (stefrheart):

no it would be the 7 x -18

OpenStudy (anonymous):

Soo....-126?

OpenStudy (goldphenoix):

Correct.

OpenStudy (stefrheart):

yes so now you equal -126 to the 13+w and it looks like 13+w=-126

OpenStudy (anonymous):

Oh so now you just solve for w like in a regular question without the fraction?

OpenStudy (stefrheart):

yes

OpenStudy (anonymous):

So -139?

OpenStudy (stefrheart):

Yes that should be correct. :)

OpenStudy (texaschic101):

(13 + w) / 7 = -18 --- multiply both sides by 7 13 + w = - 126 -- subtract 13 from both sides w = -126 - 13 w = - 139 yep...thats it

OpenStudy (stefrheart):

Do you understand now?

OpenStudy (anonymous):

Okay thanks ^-^ Yes I understand

OpenStudy (stefrheart):

Yay! Welcome! :)
