Alvin is 12 years younger than Elga. The sum of their ages is 86 what is Algas age
Ede4ka [16]

Answer:

  • Alvin: 37
  • Elga: 49

Step-by-step explanation:

Let 'a' and 'e' represent Alvin's and Elga's ages, respectively.

  a = e-12 . . . . . Alvin is 12 years younger

  a + e = 86 . . . the sum of their ages is 86

__

Substituting for 'a' gives ...

  (e -12) +e = 86

  2e = 98

  e = 49

  a = 49 -12 = 37

Alvin is 37; Elga is 49.
