Master Solving one step equations

This video tutorial explains how to solve one-step equations by isolating the variable. It covers the four basic operations: addition, subtraction, multiplication, and division, and their inverse operations. The tutorial provides examples of solving equations using these operations, including handling fractions. The goal is to either add or subtract to zero or multiply or divide to one, ensuring the variable is isolated.

What is the main goal when solving a one-step equation?

• To make the equation more complex

• To isolate the variable

• To eliminate all numbers

• To add more variables

Which operation is the inverse of addition?

• Addition

• Division

• Multiplication

• Subtraction

If you have the equation X + 4 = 11, what should you do to isolate X?

• Add 4 to both sides

• Subtract 4 from both sides

• Divide both sides by 4

• Multiply both sides by 4

In the equation Y - 7 = 3, what operation will help you solve for Y?

• Divide both sides by 7

• Multiply both sides by 7

• Add 7 to both sides

• Subtract 7 from both sides

What is the result of dividing both sides of the equation 3W = 36 by 3?

• W = 0

• W = 12

• W = 9

• W = 108

How do you solve the equation P/5 = -2?

• Divide both sides by 5

• Multiply both sides by 5

• Subtract 5 from both sides

• Add 5 to both sides

What is the reciprocal of 2/3?

• 1/3

• 3/2

• 2/3

• 1/2

How do you solve the equation 2/3Y = 4 using the reciprocal?

• Divide both sides by 3/2

• Multiply both sides by 2/3

• Divide both sides by 2/3

• Multiply both sides by 3/2

When adding fractions, what must be true about the denominators?

• They must be prime numbers

• They must be different

• They must be the same

• They must be even numbers

What is the result of adding 1/6 and 2/3?

• 3/6

• 5/6

• 7/6

• 1/2
