58 as many marbles as Elyse. After Simon gave away 49 marbles, he had 91 less marbles than Elyse. How many marbles did Elyse have?

5 u - 49 |
8 u |
Elyse had 91 more marbles than Simon in the end. So, if Simon had another 91 marbles, he would have the same number of marbles as Elyse.
8 u = 5 u - 49 + 91
8 u - 5 u = 91 - 49
3 u = 42
1 u = 42 ÷ 3 = 14
Number of marbles that Elyse had at first
= 8 u
= 8 x 14
= 112
Answer: 112
