Let's represent Elga's age as x. Since Alvin's age is three times Elga's age, we can represent Alvin's age as 3x. The sum of their ages is 76, so we can create an equation: x + 3x = 76. Combining like terms, we get 4x = 76. Dividing both sides by 4, we find x = 19. Therefore, Elga's age is 19 years old.

a = 3e
a + e = 76
∴ 3e + e = 76
e = 76/4
e = 19
∴ a = 3 × 19
a = 57
Alvin is 57 years old, and Elga is 19
alvin is 9 years younger than elga the sum of there age is 53 how old is elga
Elga is 24, because this would mean that Alvin's age is 48, and 24+48=72.

c + j = 42; c + 5 = 3(j + 5) c = 42 - j so 42 - j + 5 = 3j + 15 ie 47 - j = 3j + 15 ie 4j = 32 so Jared is 8 and Chim 34 and in 5 years Jared will be 13 and Chim 39. QED

1. Rakhi age is x Mother age 4x 2. after 5 years Rakhi age is x+5 Mother age is 3 (x+5) From 1 and 2 mother age after 5 years 4(x+5) = 3 (x+5) 4x + 20 = 3x + 15 x = 5 So the current age (i.e., after 5 years) Rakhi age = x+5 = 5 + 5 = 10 yrs Mother age = 4 (x+5) = 4 (5+5) = 40 yrs
