Solving One Step Equations with Negatives

What is the main goal when solving one-step equations?

• To make both sides of the equation different

• To isolate the variable and keep the equation balanced

• To add more variables to the equation

• To remove the equal sign

What does the multiplication property of equality state?

• If you add the same number to both sides of an equation, it remains equal

• If you multiply both sides of an equation by different numbers, it remains equal

• If you multiply both sides of an equation by the same number, it remains equal

• If you subtract the same number from both sides of an equation, it remains equal

What is a reciprocal?

• A number that is subtracted from another number

• A number that is added to another number

• A fraction where the numerator and denominator are flipped

• A fraction where the numerator and denominator are the same
