o = orange marbles
y = yellow marbles
There are 97 marbles in the bag mean:
o + y = 97
There are 25 more yellow marbles than orange marbles mean:
y = o + 25
Now:
o + y = 97
Replace y with o + 25
o + o + 25 = 97
2 o + 25 = 97
2 o = 97 - 25
2 o = 72
o = 72 / 2 = 36
y = o + 25 = 36 + 25 = 61
36 orange marbles and 61 yellow marbles
A bag is filled with yellow and orange marbles. There are 97 marbles in the bag. If there are 25 more
yellow marbles than orange marbles, find the number of yellow marbles and the number of orange
marbles in the bag.
