112 stickers
Step-by-step explanation:
Let x and y represent the number of stickers Sheryl and Jennifer were given at first.
Sheryl and Jennifer were given the same number of sticker at first.
So;
x = y 1
After jennifer used 84 stickers ,sherly had 4 times as many stickers as jennifer.
x = 4(y-84)
x = 4y - 336 2
Substituting equation 1 into 2
y = 4y - 336
Solving for y;
4y - y = 336
3y = 336
y = 336/3
y = 112
Therefore, sherly was given 112 stickers at first
