Okay, so the total cookies is given by 22 cookies (the ones given to the students) plus 27 cookies (the ones left over) Therefore there were 49 cookies in total. Subtract the 24 cookies from the first batch, and you have 25 cookies remaining, which is the total from the second batch. 

25 cookies.

24 cookies in the first batch
Unknown in the second, let's call it "x".
The total amount of cookies is the amount of cookies eaten by students (22) as well as the amount left (27).
We can set these equivalent to one another:
24+x=22+27
24+x=49
subtract 24 from both sides
24+x=49
-24     -24
x=25
So, there were 25 cookies in the second batch.

How do I solve for -31 -8r = -3(5r -6)
Dennis_Churaev [7]
Our current equation is:
-8r -31 = -3(5r -6)
To solve for this, we need to get r on one side of the equation and then simplify if needed.
On the right side of the equation, we have a pending Distributive Property, which is when you multiply the number/variable outside of the parenthesis by all numbers/variables in the parenthesis.
Let's simplify this Distributive Property to help understand our equation better.
-3(5r -6)
Multiply -3 by each number/variable separately (unless they are already being multiplied, like 2x, 1/2x, etc).
-3(5r) + -3(-6).
-3(5r) = -15r
-3(-6) = 18 (both negatives need to be in parenthesis to keep a product as negative, and if you do not multiply them in that way, you will end up with a positive product).
Your equation now is:
-8r -31 = -15r + 18
Add 15r to both sides to get r on one side.
7r -31 = 18 is now our current equation.
Add 31 to both sides to get 7r by itself.
7r = 49 is now our equation.
r is still being multiplied by 7, so we need to do the opposite of multiplying by 7.
Divide both sides by 7.
r = 7.
I hope this helps!
