How Do You Solve a Decimal Inequality Using Addition?
Note:
To solve an inequality containing decimals for a variable, focus on isolating that variable on one side of the inequality. In this tutorial, you'll see how to add decimals in order to isolate the variable and find the answer to the inequality!
Background Tutorials
-
Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

What's the Addition Property of Inequality?
Ever wondered what rules you're allowed to follow when you're working with inequalities? Well, one of those rules is called the addition property of inequality, and it basically says that if you add a number from one side of an inequality, you have to add that same number from the other side of the inequality as well. Watch the tutorial to see how this looks in terms of algebra!
