-3/5+8/5k-(3k-2)<0

OpenStudy (mertsj):

Need to rewrite it so it is clearer.

OpenStudy (mertsj):

\[\frac{-3}{5}+\frac{8}{5}k-(3k-2)<0\]

OpenStudy (mertsj):

Let's multiply each term by 5 and get rid of those miserable fractions.

OpenStudy (mertsj):

\[-3+8k-5(3k-2)<0\]

OpenStudy (mertsj):

Now we need to remove the parentheses

OpenStudy (mertsj):

\[-3+8k-15k+10<0\]

OpenStudy (mertsj):

Collect the like terms

OpenStudy (mertsj):

\[7-7k<0\]

OpenStudy (mertsj):

Subtract 7 from both sides.

OpenStudy (mertsj):

\[-7k<-7\]

OpenStudy (mertsj):

Divide by negative 7 and reverse the inequality symbol.

OpenStudy (mertsj):

\[k>1\]
