14 of the white flags and 67 purple flags, there was an equal number of white and purple flags left. How many white flags did he have at first?

Total |
Before |
4 u |
3 u + 67 |
193 |
Change |
- 1 u |
- 67 |
|
After |
3 u |
3 u |
|
Total number of flags at first
= 4 u + 3 u + 67
= 7 u + 67
7 u + 67 = 193
7 u = 193 - 67
7 u = 126
1 u = 126 ÷ 7 = 18
Number of white flags that Fred had at first
= 4 u
= 4 x 18
= 72
Answer(s): 72
