Solving literal equations

The video tutorial explains how to solve equations by isolating variables. It begins with a simple example of solving for Y, demonstrating the process of undoing addition and subtraction, followed by division to isolate the variable. The tutorial then applies the same principles to a more complex equation, solving for H. The instructor emphasizes understanding the operations affecting the variable and systematically reversing them to achieve the solution.

What is the first step in solving the equation X = 3 + 212 for 'y'?

• Add 3 to both sides

• Subtract 3 from both sides

• Multiply both sides by 2

• Divide both sides by 2

After subtracting 3 from both sides in the equation X = 3 + 212, what is the next step to solve for 'y'?

• Add 3 to both sides

• Multiply both sides by 2

• Subtract 2 from both sides

• Divide both sides by 2

What is the result of dividing both sides of the equation 8 = 2y by 2?

• y = 2

• y = 16

• y = 4

• y = 8

In the equation a - 2πR² = 2πRH, what operation is used to isolate 'h'?

• Divide both sides by 2πR

• Subtract 2πR from both sides

• Multiply both sides by 2πR

• Add 2πR to both sides

In the equation a - 2πR² = 2πRH, what must be subtracted from both sides to begin solving for 'h'?

• h

• 2πR²

• a

• 2πRH
