Subtract 2: 
Second: 10
Multiply by 88: 
Add 88: 
Divide by 44: 
Subtract 2: 
Third: 5
Multiply by 88: 
Add 88: 
Divide by 44: 
Subtract 2: 
Fourth: 2
Multiply by 88: 
Add 88: 
Divide by 44: 
Subtract 2: 
On a general terms:
Let the number be x.
Multiply by 88: 
Add 88: 
Divide by 44: 
Subtract 2: 
Notice that for every input x, the result is 2x
Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i

Answer:
9/4
Step-by-step explanation:
Hey there!
Let's plug in our values:
3(-2) - 4(1) =
-6-4 =
-10.
Hope this helps!
