Solving Two Step Equations

What is the primary goal when solving two-step equations?

• To simplify the equation as much as possible

• To isolate the variable on one side of the equation

• To perform addition and subtraction only

• To eliminate all variables

What are inverse operations used for in two-step equations?

• To isolate the variable by undoing the existing operations

• To reverse the entire equation

• To multiply the terms

• To add complexity to the equation

What inverse operation is used to counteract addition in two-step equations?

• Subtraction

• Multiplication

• Division

• Addition

In the first example, what operation is performed first to start isolating the variable?

• Addition

• Subtraction

• Multiplication

• Division

After subtracting 10 in the first example, what is the next step?

• Multiply both sides by 4

• Add 4 to both sides

• Subtract 4 from both sides

• Divide both sides by 4

How do you verify if the solution to an equation is correct?

• By substituting the solution back into the original equation

• By checking if the equation still has a variable

• By solving the equation again

• By asking someone else to solve it

What is the result of solving the equation in example two?

• p = -30

• p = 30

• p = -10

• p = 10

In example three, what operation is used to eliminate the division by 3?

• Addition

• Subtraction

• Division

• Multiplication

What is the final value of p in example four?

• p = -21

• p = 21

• p = -7

• p = 7

Which of the following is a key takeaway from the video on solving two-step equations?

• Equations cannot contain negative numbers

• Ignore the signs of numbers

• Isolate the variable using inverse operations

• Always use multiplication
