The question involves solving a simple addition equation in mathematics. It involves subtracting from both sides of an equation to solve for a variable, in this case, 'x'. The answer to the equation 172,090 = 171,090 + x is 1,000.
This question appears to be requesting the resolution of a simple addition equation. Given that we have 172,090 = 171,090 + x, the missing variable x can be found by subtracting 171,090 from both sides of the equation which will give you x = 1,000.
Remember that in any equation, the aim is to isolate the variable on one side. In this case, the variable is x. By doing so, you are able to find the value that the variable represents.
The equation you just solved is a basic algebra equation. Principles of algebra dictate that you can perform the same operation on both sides of the equation to maintain equality.

Step-by-step explanation:
Devin has 15 nickel coins and 5 quarter coins.
Step-by-step explanation:
Total worth = 200 cents
1 nickel = 5 cents
1 quarter = 25 cents
Let,
Nickels = x
Quarters = y
According to given statement;
5x+25y=200 Eqn 1
x = 3y Eqn 2
Putting x=3y in Eqn 1
Dividing both sides by 40
Putting y=5 in Eqn 2
Devin has 15 nickel coins and 5 quarter coins.
