Solving Basic Algebraic Equations

The video tutorial explains how to find an unknown number in an equation. It begins with an introduction to the concept, followed by steps to simplify the equation by dropping down known values. The tutorial then demonstrates how to isolate the variable y by performing operations on both sides of the equation. After finding the solution, the video verifies it by substituting the value back into the equation. The tutorial concludes with a reference to the Becca curriculum, ensuring the steps align with educational standards.

What is the first step in solving an equation with an unknown number?

• Subtract all numbers from each other

• Drop down what you don't know and figure out what you do

• Guess the unknown number

• Add all numbers together

In the equation 6 + 10 = 16, what is the known value?

• All of the above

• 6

• 10

• 16

What operation should be performed to isolate 'y' in the equation y - 4?

• Multiply by 4

• Add 4

• Divide by 4

• Subtract 4

Why do we add 4 to both sides of the equation y - 4 = 16?

• To check if the equation is correct

• To cancel out the -4 and isolate y

• To make both sides equal

• To make the equation more complex

What is the result of 16 + 4 in the equation?

• 20

• 18

• 24

• 22

After isolating 'y', what should the equation look like?

• y = 16

• y = 10

• y = 20

• y = 24

How can you verify if y = 20 is correct?

• By guessing

• By substituting 20 back into the original equation

• By asking a friend

• By using a calculator

What should the equation look like after substituting y = 20?

• 20 - 4 = 6 + 10

• 20 + 4 = 6 + 10

• 20 - 4 = 10 + 6

• 20 + 4 = 10 + 6

What is the result of 20 - 4?

• 14

• 20

• 16

• 18

What is the result of 6 + 10?

• 18

• 14

• 20

• 16
