8n-23n=-190n_{2}
Subtract 23n from both sides.
-15n=-190n_{2}
Combine 8n and -23n to get -15n.
\frac{-15n}{-15}=-\frac{190n_{2}}{-15}
Divide both sides by -15.
n=-\frac{190n_{2}}{-15}
Dividing by -15 undoes the multiplication by -15.
n=\frac{38n_{2}}{3}
Divide -190n_{2} by -15.
23n-190n_{2}=8n
Swap sides so that all variable terms are on the left hand side.
-190n_{2}=8n-23n
Subtract 23n from both sides.
-190n_{2}=-15n
Combine 8n and -23n to get -15n.
\frac{-190n_{2}}{-190}=-\frac{15n}{-190}
Divide both sides by -190.
n_{2}=-\frac{15n}{-190}
Dividing by -190 undoes the multiplication by -190.
n_{2}=\frac{3n}{38}
Divide -15n by -190.
