Imaginary Numbers and Equations

The video tutorial explains how to solve equations involving complex numbers by separating real and imaginary parts. It demonstrates solving for variables x and y by equating the real parts and imaginary parts separately. The tutorial includes a practice example to reinforce the concept.

What is the equation given in the introduction?

• 8 + 15i = 2x + 3y

• 8 + 15i = 2x + 3yi

• 8 + 15 = 2x + 3yi

• 8 + 15i = 2x + 3y + i

Which part of the equation contains the imaginary number?

• The part with i

• The part with 8

• The part with y

• The part with x

How do you solve for x in the equation 8 + 15i = 2x + 3yi?

• Divide 8 by 3

• Multiply 8 by 2

• Divide 8 by 2

• Subtract 8 from 2

What is the value of y when 15i is divided by 3i?

• 3

• 6

• 4

• 5

In the practice example, what is the equation given?

• 24 - 12i = 3x + 6y + i

• 24 - 12i = 3x + 6y

• 24 - 12i = 3x + 6yi

• 24 - 12 = 3x + 6yi

How do you find x in the practice example equation?

• Divide 24 by 6

• Subtract 24 from 3

• Multiply 24 by 3

• Divide 24 by 3

What is the value of y when -12i is divided by 6i?

• -1

• -2

• -3

• -4

What is the final value of x in the practice example?

• 7

• 6

• 8

• 9
