Question

Hannah and anthony are siblings who have ages that are consecutive odd integers. The sum of there ages is 92. Which equations could be used to find Hannahs age, h, if she is the older sibling?

Answer 1

If you would like to know the equation that could be used to find Hannah's age, you can calculate this using the following steps:

h ... Hannah's age ... h = a + 2
a ... Anthony's age ... a = h - 2

a + h = 92
h - 2 + h = 92
2 * h - 2 = 92
2 * h = 92 + 2
2 * h = 94       /2
h = 94 / 2 = 47

a = h - 2 = 47 - 2 = 45

The correct result could be h - 2 + h = 92.
