Here is the equation\[\frac{ 4 }{ 5 }+x=\frac{ 3 }{ 7 }\] To get the x term alone you need to subtract 4/5 from both sides. Here is what you will have now\[x=\frac{ 3 }{ 7 }-\frac{ 4 }{ 5 }\]
OpenStudy (anonymous):

35
OpenStudy (4everaddicted2anime):
Okay. To do that you needed to multiply 5 by 7 and 7 by 5 correct?
OpenStudy (anonymous):
yes
OpenStudy (4everaddicted2anime):
This means that you need to multiply 3 by 5 and 4 by 7. After doing this you should get\[x=\frac{ 15 }{ 35 }-\frac{ 28 }{ 35 }\]
OpenStudy (anonymous):
