Question

An older person is nine years older than eight times the age of a younger person the sum of their ages is 45 find their ages

Answer 1

x=8+9y

x+y = 45

8 +9y +y = 45

10y =37

y = 3.7 years old = younger guy's age

x = 45 -3.7 = 41.3 years old = older guy's age

check

8 + 9(3.7) = 8+33.3 = 41.3
