Solving a multi step equation by combining like terms

The video tutorial explains how to solve a multi-step equation by isolating the variable. It begins by identifying the need to simplify the equation by combining like terms. The tutorial then demonstrates using inverse operations to solve for the variable. Finally, it verifies the solution by substituting it back into the original equation to ensure correctness.

What is the primary goal when solving a multi-step equation?

• To find the value of the variable

• To add more variables

• To make both sides of the equation equal

• To eliminate all numbers

Why is it necessary to combine like terms in an equation?

• To make the equation more complex

• To simplify the equation

• To increase the number of variables

• To change the variable

If you have -3X and -6X on the same side of an equation, what is the result when you combine them?

• -3X

• 9X

• 3X

• -9X

What operation is used to isolate the variable when it is multiplied by a number?

• Subtraction

• Multiplication

• Division

• Addition

How can you verify that your solution to an equation is correct?

• By adding more terms

• By changing the variable

• By substituting the solution back into the original equation

• By guessing
