I need someone to double check my answer. Problem in the comments.

OpenStudy (anonymous):

\[-\frac{ 13 }{ 4 } - \frac{ 3 }{ 2 }(\frac{ 3 }{ 4 }j - \frac{ 4 }{ 5 }) = -\frac{ 14 }{ 5 }\] \[-\frac{ 13 }{ 4 } - \frac{ 9 }{ 8 }j + \frac{ 12 }{ 10 } = -\frac{ 14 }{ 5 }\]

OpenStudy (anonymous):

\[- \frac{ 13 }{ 4 } + \frac{ 12 }{ 10 } + \frac{ 14 }{ 5 } = \frac{ 9 }{ 8 }j\]\[\frac{ -25 }{ 10 } = \frac{ 9 }{ 8 }j\]

OpenStudy (anonymous):

edit: -25/20

OpenStudy (anonymous):

I got a different answer when adding those three terms

OpenStudy (anonymous):

what you got?

OpenStudy (anonymous):

LCD is 20 so it's \[-65/20 + 24/20 + 56/20\]

OpenStudy (anonymous):

So \[15/20 = 9j/8\]

OpenStudy (anonymous):

\[\frac{ 3 }{ 4 }=\frac{ 9 }{ 8 }j\]

OpenStudy (anonymous):

Do you know how to find the least common denominator @Sadworld ?

OpenStudy (anonymous):

I know, I just skipped a number accidently

OpenStudy (anonymous):

It's ok we all make mistakes. :)

OpenStudy (anonymous):

2/3 = j?

OpenStudy (anonymous):

yup @Sadworld

OpenStudy (anonymous):

thanks :D Wish I could give you both a medal
