Question

The ages Edna, and Elsa are consecutive integers. The sum of their ages is 114. What are their ages?

Answer 1

Answer:

Edna = 56.5

Elsa = 57.5

Step-by-step explanation:

Represent Edna age with x; Elsa age will be x + 1

So,

$x + x + 1 = 114$

$2x + 1 = 114$

Make 2x the subject

$2x = 114 - 1$

$2x = 113$

Solve for x

$x = 113/2$

$x = 56.5$

Elsa age is calculated as thus;

$Elsa = x + 1$

$Elsa = 56.5 + 1$

$Elsa = 57.5$
