Question

Walter lived 2 years longer than his brother Martin. Walter was 79 at the time of his death. Which equation could be used to find Martin's age, a, at the

time of his death?
O a + 2 = 79
O 79 + 2 = a
O 79 + a = 2
O a- 79 = 2

Answer 1

To find Martin's age at the time of his death, we can set up the equation: Walter's age = Martin's age + 2. Since we know that Walter lived 2 years longer than Martin and Walter was 79 at the time of his death, we can solve for Martin's age by subtracting 2 from 79.

Step-by-step explanation:

To find Martin's age at the time of his death, we can set up the equation:

Walter's age = Martin's age + 2

Since we know that Walter lived 2 years longer than Martin and Walter was 79 at the time of his death, we can substitute the values into the equation:

79 = Martin's age + 2

To solve for Martin's age, we subtract 2 from both sides of the equation:

Martin's age = 79 - 2 = 77

Answer 2

79+2=a is the correct answer
