Solving Two-Step Equations

The video tutorial introduces solving one-variable two-step equations using numbers and letters. It demonstrates solving the equation 2x - 4 = 6 by adding 4 to both sides, resulting in 2x = 10, and then dividing by 2 to find x = 5. The tutorial also explains using tiles and zero pairs to visualize the process, emphasizing the importance of performing operations on both sides of the equation. The lesson concludes with encouragement for students to continue practicing and mastering the concept.

What is the first step in solving a two-step equation?

• Divide both sides by the variable

• Multiply both sides by 2

• Square both sides

• Add or subtract to isolate the variable term

In the equation 2x - 4 = 6, what should be added to both sides first?

• 6

• 2

• 4

• 10

After adding 4 to both sides of 2x - 4 = 6, what is the resulting equation?

• 2x = 10

• 2x = 6

• 2x = 12

• 2x = 8

What is the first step in solving the equation 2x - 4 = 6?

• Multiply both sides by 2

• Add 4 to both sides

• Subtract 4 from both sides

• Divide both sides by 2

What is the purpose of using tiles and zero pairs in solving equations?

• To add more variables

• To make the equation more complex

• To change the equation completely

• To visually represent and simplify the equation

What is a zero pair in the context of solving equations?

• A pair of variables

• A pair of solutions

• A pair of equations

• A pair of numbers that add up to zero

What is the significance of the zero pair in solving equations?

• It complicates the equation

• It helps in visualizing and simplifying the equation

• It adds more variables

• It changes the equation completely

When using zero pairs, what happens to the negative numbers?

• They are added to the other side

• They are doubled

• They cancel out with their positive counterparts

• They are ignored

After simplifying with zero pairs, what is the equation before dividing?

• 2x = 8

• 2x = 6

• 2x = 12

• 2x = 10

What should you do if you encounter a negative number while using zero pairs?

• Ignore it

• Subtract it from the other side

• Add a positive number to cancel it out

• Multiply it by zero
