Understanding Multi-Step Inequalities
Before we can tackle the strategies for solving multi-step inequalities, it's essential to understand what they are. A multi-step inequality is an expression that involves at least two operations, such as addition, subtraction, multiplication, or division, and compares values using inequality symbols: <, >, β€, or β₯.
Key Components of Multi-Step Inequalities
- Variable: A symbol (usually a letter) that represents an unknown number.
- Coefficients: Numbers multiplied by the variables.
- Constants: Fixed numbers that donβt change.
For example, in the inequality 3x + 5 < 14, 3 is the coefficient of the variable x, 5 is the constant, and < is the inequality sign.
Steps to Solve Multi-Step Inequalities
Now that we understand the basics, let's break down the steps to solve multi-step inequalities.
Step 1: Isolate the Variable
Just like in regular equations, the first step is to isolate the variable. This typically involves the following operations:
- Subtraction or addition: Move constants to the other side of the inequality.
- Division or multiplication: When multiplying or dividing by a negative number, remember to flip the inequality sign! π
Example:
- Start with the inequality: 3x + 5 < 14
- Subtract 5 from both sides:
3x < 9 - Divide by 3:
x < 3
Step 2: Check Your Solution
Itβs always a good idea to check your solution. You can pick a number less than the value you found (in this case, 3) and substitute it back into the original inequality to ensure it holds true. For instance, if you choose 2:
3(2) + 5 < 14
6 + 5 < 14
11 < 14 (True)
Important Notes
"Always remember to reverse the inequality sign when multiplying or dividing by a negative number. This is a common mistake that can lead to incorrect answers!"
Example Problems to Try
To practice your skills, consider the following multi-step inequalities:
- 2x - 4 β₯ 10
- -3(x + 2) < 6
- 5 + 2y > 3y - 1
Solutions:
-
2x - 4 β₯ 10
Add 4: 2x β₯ 14
Divide by 2: x β₯ 7 -
-3(x + 2) < 6
Distribute: -3x - 6 < 6
Add 6: -3x < 12
Divide by -3 (reverse the sign): x > -4 -
5 + 2y > 3y - 1
Subtract 2y: 5 > y - 1
Add 1: 6 > y or y < 6
