Each sheet had 6 stickers
Step-by-step explanation:
Given that Sandy had 6 sheets of animal stickers with each sheet having equal number of stickers
Lets assume each sheet had x number of stickers, so for all 6 sheets, you have 6x animal stickers.
A friend gave him 4 more animal stickers, this will mean 6x + 4
The total number of animal stickers is now 40, this means 6x+4 =40
Solving the equation,
6x+4=40 -----------------collect like terms
6x=40-4
6x=36 ---------------------divide by 6 both sides to remain with x
6x/6=36/6
x=6
So, initially, each of the 6 sheets had 6 animal stickers.
