How To Solve One - Step Equations (Addition & Subtraction)

The video tutorial demonstrates how to solve algebraic equations using algebra tiles. It begins with solving X + 1 = 3, showing both the algebra tile method and the traditional method. The tutorial then moves on to solve P - 5 = -2 and Y + 4 = -7, using similar techniques. Each example is followed by a verification step to ensure the solution is correct. The video emphasizes the importance of balancing equations and visualizing them with tiles.

What does the green tile represent in the algebra tile method?

• The number 1

• The variable X

• The number 3

• The equal sign

How do you isolate X in the equation X + 1 = 3 using traditional methods?

• Multiply both sides by 2

• Subtract 1 from both sides

• Add 1 to both sides

• Divide both sides by 3

What is the first step in solving P - 5 = -2 using algebra tiles?

• Remove 2 red tiles from both sides

• Add 2 yellow tiles to both sides

• Add 5 red tiles to both sides

• Add 5 yellow tiles to both sides

What is the solution for P in the equation P - 5 = -2?

• P = 5

• P = 0

• P = 3

• P = -3

In the equation y + 4 = -7, what operation is needed to isolate Y using algebra tiles?

• Remove 7 red tiles

• Add 4 yellow tiles

• Add 7 yellow tiles

• Add 4 red tiles

What is the solution for Y in the equation y + 4 = -7?

• Y = -3

• Y = -11

• Y = 3

• Y = 11

How do you verify the solution for Y in the equation y + 4 = -7?

• Substitute Y with 0

• Substitute Y with -11

• Substitute Y with 7

• Substitute Y with 4
