.4X-.2=1 if u dont like dealing with the tenths decimal digit multiply every thing by 10
4x-2=10 solve like normal add 2
4x=12divide by 4
highlight%28x=3%29

%286%2FX%29-.12=.48 if u dont like dealing with the hundredths decimal digits then multiply everything by 100.
%28600%2FX%29-12=48add 12
%28600%2FX%29=60 multiply both sides by X
600=60Xdivide by 60
highlight%2810=X%29
