11=-q
OpenStudy (anonymous):
Try to get rid of the denominator first by multiplying everything by that number.
Then divide by the coefficient of the variable.

so the answer for 11=-q
OpenStudy (anonymous):
That one has no denominator, so you can just divide both sides by the coefficient of q which is -1. So,
q = -11
OpenStudy (saifoo.khan):
q = -11
OpenStudy (saifoo.khan):
lol, idk.. by solving! ;)

mulyply both by -2?
OpenStudy (anonymous):
Multiply both sides by 5 to get
10q = 7
Divide both sides by 10 to get
q = 7/10
OpenStudy (saifoo.khan):
q = 7/10
OpenStudy (saifoo.khan):
simply use that cross multiply thing.
OpenStudy (anonymous):
show me on that thing

-7b=0
OpenStudy (saifoo.khan):
b = 0
OpenStudy (anonymous):
Or, for this one, since only the right side has a denominator, you can just skip the first step and divide both sides by 2 to get
q = 7/10
OpenStudy (saifoo.khan):
okay!
OpenStudy (anonymous):
thanx
