If 32w (40w) =
1000000w-10 ; Find w.
Solution
52w (40w) =
1000000 w-10
(52)w (40w)
= 106(w-10)
(25)w (40w) =
106w-60
(25 x 40)w = 106w-60
(1000)w = 106w-60
(103)w = 106w-60
3w = 6w-60
0= 6w-3w – 60 [collecting letters together]
0= 3w – 60 [collecting letters together]
60 = 3w
2060= 3w [dividing by 3 on both sides]
w = 20

If 42t (4t) =
128t+5 ; Find t.
