How to Solve in Terms of a Variable

The video tutorial guides viewers through solving an algebraic equation to isolate the variable Q in terms of P and R. It begins with a problem statement and proceeds with a detailed explanation of the steps needed to manipulate the equation. The tutorial emphasizes the importance of performing opposite operations to move terms across the equal sign, ultimately leading to the solution Q = (2 + 3R) / P. The video concludes with a summary of the solution process.

What is the initial equation given in the problem?

• P*Q - 2 = 3R

• P*Q = 2 + 3R

• P*Q - 3R = 2

• P*Q + 3R = 2

What operation should be performed first to start isolating Q?

• Divide both sides by P

• Multiply both sides by P

• Add 3R to both sides

• Subtract 3R from both sides

After adding 3R to both sides, what does the equation become?

• P*Q = 3R - 2

• P*Q = 2 + 3R

• P*Q = 3R + 2

• P*Q = 2 - 3R

What is the final step to isolate Q in the equation?

• Multiply both sides by P

• Add P to both sides

• Subtract P from both sides

• Divide both sides by P

What is the expression for Q in terms of P and R?

• Q = (2 - 3R) * P

• Q = (2 + 3R) / P

• Q = (2 + 3R) * P

• Q = (2 - 3R) / P
