In the given problem, apply your knowledge in algebra and basic mathematics specially in solving word problem about mathematical equation and unknown variables.

4.) Find the three consecutive odd integers whose sum is 222.

let

x → first odd integer

x + 2 → second odd integer

x + 4 → third odd integer

x + (x+2) + (x+4) = 222

3x + 6 = 222

3x = 222 - 6

3x = 216

x = 216/3

x = 72

x+2 = 74

x+4 = 76

Answer

72, 74, 76 (it is not odd integers), there is no 3 consecutive odd integers having a sum of 222.

5.) Carlo is now 10 years older than Edison. In 5 years, he will be twice as old as Edison's age. What are their present ages?

let x is the age of Edison

x + 10 → Carlo's age

Five years

x + 5 → Edison

2(x+5) → Carlo

x + 10 + 5 = 2(x+5)

x + 15 = 2x + 10

2x - x = 15 - 10

x = 5

x+10 = 15

Answer

Edison's age is 5 years old

Carlo's age is 15 years old
