The problem says:
D = E+32 I'll use this value for D below
E+8 = 3/7D
------------------
E+8 = 3/7(E+32)
7E+56 = 3(E+32)
7E+56 = 3E+ 96
4E = 40
E = 10 Elizabeth colored 10 pages
D = E+32 = 10+32 = 42
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check:
E+8 = 3/7D
10+8 = 3/7(42)
18 = (42*3)/7 =
18 = 18 Correct
