Elijah had some coins at first. After he bought another 65 coins, he had six times as many coins as before. How many coins did Elijah have at first?
| |
Coins |
| Before |
1 u |
| Change |
+ 65 |
| After |
1 u + 65 = 6 u |
Number of coins after he bought = 1 u + 65
Number of coins that is six times as many coins as before = 6 x 1 u = 6 u
6 u = 1 u + 65
6 u - 1 u = 65
5 u = 65
1 u = 65 ÷ 5 = 13
Number of stickers that Kim had at first
= 1 u
= 13
Answer(s): 13
