How Do You Solve a Decimal Inequality Using Subtraction?
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 subtract 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.

Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
