Answer:
Edna = 56.5
Elsa = 57.5
Step-by-step explanation:
Represent Edna age with x; Elsa age will be x + 1
So,
[tex]x + x + 1 = 114[/tex]
[tex]2x + 1 = 114[/tex]
Make 2x the subject
[tex]2x = 114 - 1[/tex]
[tex]2x = 113[/tex]
Solve for x
[tex]x = 113/2[/tex]
[tex]x = 56.5[/tex]
Elsa age is calculated as thus;
[tex]Elsa = x + 1[/tex]
[tex]Elsa = 56.5 + 1[/tex]
[tex]Elsa = 57.5[/tex]
