Opal had the same number of silver, red and white stamps at first.
Total number of stamps in the end
= 1 u + 5 u + 5 u - 19
= 11 u - 19
11 u - 19 = 234
11 u = 234 + 19
11 u = 253
1 u = 253 ÷ 11 = 23
Number of white stamps that Opal had at first
= 5 u - 19 + 57
= 5 u + 38
= 5 x 23 + 38
= 153
Answer(s): 153
