yes?

-5(3-q) +4 = 5q-11
OpenStudy (stefrheart):
you need to distribute the -5
OpenStudy (anonymous):
Okay so it would be -15 - 5q + 4 = 5q -11?
OpenStudy (stefrheart):
yes! :)

Okay! so would i add the 15 to both sides now?
OpenStudy (stefrheart):

OpenStudy (anonymous):

Okay so -5q + (-11) =5q -11?
OpenStudy (anonymous):
I think
OpenStudy (stefrheart):
wait we made a mistake when it was -5*-q it should be 5q not -5q
OpenStudy (anonymous):
Oh right i just saw the subtraction sign and thought of it as a -
OpenStudy (stefrheart):
its okay but this would be all real numbers as the answer

Okay
OpenStudy (stefrheart):
Do you understand why?
OpenStudy (anonymous):
Oh yeah because it's 5q - 11 = 5q- 11 so the answer just goes on. Would it work if I said infinity answers?
OpenStudy (stefrheart):
Yes but the most logical mathematical answer you can do is all real numbers its more mathematical than infinity answers
