Question

Huilan's age is two times thomas's age. The sum of their ages is 45.what is thomas's age

Answer 1

Answer: Thomas’ age is 15

Step-by-step explanation:

T + 2T = 45

3T = 45

Divide both sides by 3

T = 15

Answer 2

Thomas is 15 years old.

Solution:

Assume Hulian's age as H and Thomas's age as T,

Given, Huilan's age is two times Thomas's age
`\Rightarrow H=2T \rightarrow (1)`

The sum of their ages is 45
`\Rightarrow H+T=45 \rightarrow (2)`

On substituting (1) in (2) we get,
`(H=2T)`

`2T+T=45`

On adding the common terms,

`3T=45 \Rightarrow T=(45)/(3)`

On dividing 45 and 3 we get,

`\therefore T=15`
