its - y over 8
for any who didn't know
OpenStudy (anonymous):
subtract 1 from both sides
then multiply both sides by \(-1\)
OpenStudy (anonymous):
clear or no?
OpenStudy (anonymous):
You can either get a common denominator (8), or you could move the one over and then cross multiply.
OpenStudy (anonymous):
\[\frac{ -y }{ 8 }+\frac{ 1 }{ 1 }=\frac{ -5 }{ 1 }\]

satellite does it equal 6?
OpenStudy (anonymous):
there is no such mathematical operations as "move"
neither is there "cross multiply
OpenStudy (anonymous):
\[\frac{ -y }{ 8 }=\frac{ -6 }{ 1 }\]
OpenStudy (anonymous):
You subtract 1 from each side and then you multiply both sides by 8 and then -y=?
OpenStudy (anonymous):
no \[-\frac{y}{8}+1=-5\] subtract \(1\) get \[-\frac{y}{8}=-6\]

yes
OpenStudy (anonymous):
then multiply both sides by \(-8\)
OpenStudy (anonymous):
i meant "no, it is not 6"
OpenStudy (anonymous):
and also where did the 1 come from if you got rid of it?
OpenStudy (anonymous):
\[-y=-42\]
\[y=42\]

OpenStudy (anonymous):
the 1 was in the question
got rid of it by subtracting 1 from both sides of the equation
OpenStudy (anonymous):
