Alvin is 13 years younger than elga. the sum of their ages is 71. what is elgas age

42

Step-by-step explanation:

x+(x+13)=71

2x+13=71

2x=71-13

2x=58

x=29 (alvin)

71-29=42 (elga)

To solve this we can use systems of linear equations. (two equations)

a is avlins age

e is elgas age

a  + 13 = e ( simplifys to a - e = 13 )

a  + e = 71

add

a - e =   -13

a + e = 71

2a = 58

a = 29  (alvin is 29 years old)

to find elgas age... substitute a into an original equation

(29) + 13 = e

elga is 42 years old
