Solving One Step Equations with Algebra Tiles

The video tutorial explains how to solve one-step equations using visual models. It introduces the concept of using colored squares and bars to represent numbers and variables, and demonstrates solving various equations by manipulating these models. The tutorial covers changing signs when crossing the equal sign, combining positive and negative values to zero, and dividing or multiplying to isolate variables.

What does a yellow square represent in the modeling of equations?

• A variable X

• A variable X squared

• A positive number

• A negative number

What happens to the sign of a component when it crosses the equal sign?

• It remains the same

• It disappears

• It changes from positive to negative or vice versa

• It doubles in value

In the equation X + 2 = 4, what is X equal to after solving?

• 0

• 2

• 6

• 4

How do you solve the equation X + 4 = -3?

• X = -7

• X = 1

• X = -1

• X = 7

What is the result of X - 3 = -7?

• X = -4

• X = -10

• X = 10

• X = 4

In the equation 2X = -6, what is the value of X?

• 3

• -3

• 6

• -6

How is the equation 4X = 4 solved to find the value of X?

• X = 1

• X = 0

• X = 4

• X = 16

What is the value of X when X divided by 2 equals 4?

• 16

• 4

• 8

• 2

If X divided by 3 equals 2, what is the value of X?

• 8

• 6

• 4

• 2

What is the correct method to solve an equation where X is divided by a number?

• Subtract the number from both sides

• Add the number to both sides

• Divide both sides by the number

• Multiply both sides by the number
