i!h

OpenStudy (misty1212):

is it \[\huge \frac{x-9}{x}=\frac{2}{5}\]

OpenStudy (anonymous):

yes it is

OpenStudy (anonymous):

I have to find the x

OpenStudy (misty1212):

ok we can "cross multiply" to get \[5(x-9)=2x\]

OpenStudy (misty1212):

then the usual steps \[5x-45=2x\\ 3x-45=0\\ 3x=45\\ x=45\div 3\]

OpenStudy (misty1212):

got it?

OpenStudy (anonymous):

yes, thank you girl :)
