Solving Two-Step and One-Step Equations

This video tutorial covers solving one-step and two-step equations. It begins with an introduction to solving equations using addition and subtraction, followed by examples and practice problems. The tutorial then progresses to solving equations involving multiplication and division, and concludes with solving two-step equations. Throughout, the video emphasizes isolating the variable and checking solutions.

What is the first step in solving a one-step equation involving addition?

• Multiply both sides by the same number

• Add the same number to both sides

• Subtract the same number from both sides

• Divide both sides by the same number

If you have the equation X + 5 = 12, what should you do to isolate X?

• Multiply both sides by 5

• Subtract 5 from both sides

• Divide both sides by 5

• Add 5 to both sides

What does the addition property of equations allow you to do?

• Add or subtract the same number to both sides of an equation

• Multiply both sides of an equation by zero

• Divide both sides of an equation by zero

• Change the variable on one side of the equation

In the equation 10 = 10, what happens if you add 3 to both sides?

• The equation becomes 13 = 10

• The equation becomes 10 = 13

• The equation remains true

• The equation becomes false

How do you solve the equation Y + 1/2 = 3/4?

• Divide both sides by 2

• Add 1/2 to both sides

• Multiply both sides by 2

• Subtract 1/2 from both sides

What is the multiplication property of equations?

• You can multiply or divide each side by zero

• You can multiply or divide each side by the same nonzero number

• You can add or subtract the same number to each side

• You can change the variable on one side of the equation

How do you solve the equation 3Y = 18?

• Multiply both sides by 3

• Subtract 3 from both sides

• Add 3 to both sides

• Divide both sides by 3

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

• Simplify each side independently

• Undo multiplication and division

• Get all variable terms to one side

• Undo addition and subtraction

In a two-step equation, what should you do after simplifying each side?

• Check the solution

• Undo multiplication and division

• Undo addition and subtraction

• Get all variable terms to one side
