What is the main objective when solving the equation S = pH + 2B for B?

• To find the value of S

• To isolate B on one side of the equation

• To eliminate pH from the equation

• To solve for pH

Which term should be moved first to isolate B in the equation S = pH + 2B?

• pH

• 2B

• None of the above

• S

What operation is used to move pH to the other side of the equation?

• Addition

• Subtraction

• Multiplication

• Division

What is the result of subtracting pH from both sides of the equation?

• S + pH = 2B

• S = pH + 2B

• S - pH = 2B

• S = 2B

What operation is implied between 2 and B in the equation 2B?

• Addition

• Subtraction

• Division

• Multiplication

How do you isolate B when it is multiplied by 2?

• Divide both sides by 2

• Multiply both sides by 2

• Subtract 2 from both sides

• Add 2 to both sides

What is the final form of the equation when B is isolated?

• B = S / pH + 2

• B = S * pH / 2

• B = S - pH / 2

• B = S + pH / 2

What happens to the term 2 when dividing both sides by 2?

• It cancels out

• It doubles

• It remains 2

• It becomes 0

Why is it important to verify the final answer?

• To ensure the equation is balanced

• To find the value of pH

• To confirm the value of S

• To check if B is still in the equation

What is the correct answer choice for the final equation?

• B = S / pH + 2

• B = S * pH / 2

• B = S - pH / 2

• B = S + pH / 2
