Determine the range and then simplify using cross multiplication so u have 18(7-2n)=7+2n

18(7-2n) = 126-36n=7+2n
move the constant and variable -36n-2n=7-126 collect like terms to where the problem is now -38n=-119
divide both sides by -38 and now you have n= 119/38

DE = 4 x 0.67 = 2.68

FE = 3 x 0.67 = 2.01
