How to Solve Basic Multi-Step Equations

The video tutorial explains how to solve a multi-step equation by isolating the variable X. It emphasizes the importance of using opposite operations to move terms across the equal sign and highlights the correct order of operations. The solution is verified by substituting the value back into the equation.

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

• To make both sides of the equation equal

• To isolate the variable on one side

• To add all terms together

• To eliminate all variables

What should you do to move a term across the equal sign?

• Add the same term to both sides

• Divide the term by two

• Multiply the term by itself

• Perform the opposite operation

In the equation 2X + 3 = 12, what is the first step to isolate X?

• Add 3 to both sides

• Multiply both sides by 2

• Subtract 3 from both sides

• Divide both sides by 2

After subtracting 3 from both sides in the equation 2X + 3 = 12, what is the next step?

• Add 2 to both sides

• Subtract 2 from both sides

• Multiply both sides by 3

• Divide both sides by 2

What is the solution to the equation 2X + 3 = 12?

• X = 3

• X = 4.5

• X = 6

• X = 9
