Directions: Answer the following questions value of a = 19. b = 43 and...
Understanding the Problem
To solve the equation a + b = ? - c, we need to find the value of the expression by substituting the given values of a, b, and c.
Given Values
- a = 19
- b = 43
- c = 15
Calculating a + b
- First, we add a and b:
- a + b = 19 + 43
- a + b = 62
Rearranging the Equation
- Now, we rewrite the original equation:
- 62 = ? - 15
Finding the Value of ?
- To isolate the question mark, we need to add c (which is 15) to both sides:
- 62 + 15 = ?
- 77 = ?
Conclusion
- Therefore, the value of the expression a + b = ? - c is 77.
- The correct answer is option 'C', which is 77.
Quick Summary
- a + b = 19 + 43 = 62
- Rearranging gives us: 62 = ? - 15
- Solving for ? results in: ? = 77
This process clearly shows that the answer to the problem is 77, confirming option 'C' as correct.
