One-Step Equations (Remote)
Expressions vs. Equations
An equation is a mathematical sentence that includes an equal sign to compare two expressions.
How to Solve One-Step Equations
Your goal in solving one-step equations is to isolate the variable in the equation.
This means that you want to get the letter by itself on one side of the equation, and all of the numbers on the opposite side.
Tips
- When you solve an equation, your goal is to get the variable alone by itself on one side of the equation.
- When you are solving for a variable, you MUST use inverse operations to get the variable by itself.
- Whatever you do to one side of an equation, you must do to the other side of the equation. In other words, you must keep the equation balanced.
Examples of Inverse Operations
The opposite of adding 23: subtracting 23
The opposite of subtracting 18: adding 18
The opposite of multiplying by -15: Dividing by -15
The opposite of dividing by 8: multiplying by 8
