Answer:
4x=20+4(10); x=15
Step-by-step explanation:
20+4(10)=4x
This is where x is the number of stickers per sheet.
This is the equation because she has 20 stickers.
To find the original number of stickers, we have to add back the amount given.
She has 4 sheets and gave 10 stickers from each sheet. This means she gave away 4*10 stickers.
Now, we can solve the equation:
20+40=4x
60=4x
x=15
If you meant to write 
then the statement is true.
As a more concrete example, something like 
would be read out as "log base 3 of 81 is equal to 4".
Switch y and x: x =16y^2 + 1
Solve for y: x-1=16y^2
16y =+-√(x-1)
y =+-√(x-1)/16
-3 dollars because if i owe you 2 dollars and i give you 5 dollars back that means you now owe me 3 dollars, therefore you are negative 3 dollars
