Let the number be "x".
Equation:
x-10 = -13
x = -3
------------------
The state of indiana has approximately 2.1 million more people than Kentucky. together their population totals 10.3 million. approximately how many people are in each state? what is the solution and the equation?

I = K + 2.1 million
I + K= 10.3 million
------------------------
Substitute for I and solve for "K":
K + 2.1 + K = 10.3
2K = 8.2 million
K = 4.1 million (Kentucky population)
---
Since I = K+2.1 , I = 6.2 million (Indiana population)

Three raffle tickets are represented by three consecutive integers. if the sum of the three integers is 1,982,031, find the ticket numbers. what is the solution and the equation?
---
1st: x-1
2nd: x
3rd: x+1
----------------------------------
Equation:
x-1 + x + x+1 = 1982031
3x = 1982031
x = 660677 (the 2nd integer
x-1 = 660676 (the 1st integer)
x+1 = 660678 (the 3rd integer)
