Here's how you figure it out. It's very easy.
S_1 = shift 1
S_2 = shift 2
Set up a system of equations
S_1 = 4*S_2 (since it made 4x shift 2)
S_1 + S_2 = 5500 (since this is total production.
Now solve. There are a few ways to do this. I'll substitute S_2.
To do this use the second equation,
S_2 = 5500 - S_1
Then plug into the first.
S_1 = 4*(5500 - S_1)
S_1 = 22000 - 4*S_1
5*S_1 = 22000
>>S_1 = 4400<<

4400 jet engines.
The key to solving word problems of this type is to read carefully and see if you can set up a simple fraction.
Example:
5500/5=1100. since we know shift 1 produced 4 times shift 2 it is easy to guess that shift 1 produced 4,400 engines and shift 2 produced 1,100 engines.
Another strategy that I like to use is to write an equation that says what is happening in the word problem.
Example:
4x+x=5500
The equation says that 4 times an unknown number of jets plus the same unkown number of jets equals the total number of jets produced
The equation reduces to:
5x=5500
The equation says the total number of jets produced is 5 times greater than a certain number of jets. Logically, the unknown number is the number of jets produced by shift two.
Dividing both sides of the equation by five solves for the value of x.
(5x)/5=(5500)/5=1100
Finally, Solving for the value of x yields the number of jets produced by shift 2. If the meaning of the value of x is not apparent think logically. The original problem compared the number of jets produced by shift 1 to the number of jets produced by shift 2. The purpose of creating the equation was to solve for the number of jets produced by one of the shifts.
This method may seem tedious, but it can be effective for clarifying more complex word problems. The key to solving word problems to think logically about what the problem is asking you, and then look for what you can find with the information given.

Ok... first, you know that shift 1 is four times larger than shift 2. Therefore, you can make this formula:
x + 4x = 5,500
Make sense? Solve for x.
x = 1,100
Now, that's the output for shift 2. We want shift 1.
So... 1,100 x 4 = 4,400. That's your answer!
4,400. Good luck! :)

i'm uncertain of a greenback determine yet I do have self assurance that Obama has chosen mr. Immelt to help plan the hot "clever grid" electric powered grids for united states of america so the form would be interior the ten's to one hundred's of billions.

The KEY here is that you'd simply need to divide the total output, 5500 by 4, which would give you 4400.
