Question 388658
If the equation is {{{4= -(2/5)u}}} then 



{{{4= -(2/5)u}}} Start with the given equation.



{{{4*5= -2u}}} Multiply both sides by 5.



{{{20= -2u}}} Multiply



{{{20/(-2)= u}}} Divide both sides by -2.



{{{-10= u}}} Reduce



So the solution is {{{u=-10}}}



----------------------------------------------------



If the equation is {{{4= -2/(5u)}}} then 



{{{4= -2/(5u)}}} Start with the given equation.



{{{4*5u= -2}}} Multiply both sides by 5u.



{{{20u= -2}}} Multiply



{{{u= -2/20}}} Divide both sides by -20.



{{{u= -1/10}}} Reduce



So the solution is {{{u= -1/10}}}
