Which number should each side of the equation 4/5x=8 be multiplied by to produce he equivalent equation of x=10?
gulaghasi [49]
<< Add .\frac{-4}{5} to the left and right of the equation, multiple and make ''opposite multiplation'' to find x.

A) \frac{4}{5x}. \frac{-4}{5} = 8.  \frac{-4}{5} &#10;
\frac{16}{25x} = \frac{-32}{5}
25x.(-32)= (-16).5
-800x= -80

**to leave x alone and positive, you must divide to -800.
x=  \frac{-80}{-800}
x=  \frac{1}{10}
= INCORRECT

B) \frac{4}{5x} . \frac{1}{5} = 8. \frac{1}{5} &#10;
\frac{4}{25x} = \frac{8}{5}
25x.8= 4.5
200x=20&#10;
x=  \frac{20}{200} =  \frac{1}{10}


C)\frac{4}{5x} . \frac{5}{4}=  \frac{8.5}{4}
\frac{1}{x} = \frac{40}{4}
\frac{1}{x} =10
10x=1
x= \frac{1}{10}


D) \frac{4.5}{5x}  = 8.5
\frac{4}{x} = 40
40x= 4
x= \frac{4}{40} = 1/10

I think there is a problem with the options :D
