Question

Which equation below would be best solved by using the addition property of equality?

Options:
A. f divided by 23 = 45
B. 23f = 45
C. f + 23 = 45
D. f - 23 = 45

Answer 1

Option C: f + 23 = 45 is best solved using the addition property of equality, which involves subtracting 23 from both sides to maintain the balance of the equation, leading to the solution f = 22.

Step-by-step explanation:

The question is asking which equation would be best solved by using the addition property of equality. The addition property of equality says that you can add the same number to both sides of an equation and the equality remains true. Considering the options given, Option C: f + 23 = 45 is the one where the addition property of equality would be the most straightforwardly applicable. You would subtract 23 from both sides of the equation to solve for f, maintaining the balance of the equation.

Let's look at a step-by-step explanation:

1. Starting with the equation f + 23 = 45.
2. Subtract 23 from both sides: (f + 23) - 23 = 45 - 23.
3. Simplifying both sides gives: f = 22.
