Question

Sangay has 6 more years of teaching experienced than Dorji, and the two of them have 16 years of experienced altogether. How many years of teaching experienced does Dorji have?

Answer 1

5 years

Explanation:

Let x = Dorji's teaching experienc

x + 6 = Sangay's

x + x + 6 = 16

2x = 10

x = 5

Answer 2

Answer: Dorji has 5 years of teaching experience.

Explanation:

As per the problem, Sangay has 6 more years of teaching experience than Dorji, therefore:

S = D + 6

The sum of their teaching experience is 16 years, therefore:

S + D = 16

Now there are two equations with two variables. Substitute the value of S from the first equation into the second equation:

(D + 6) + D = 16

Now combine like terms:

2D + 6 = 16

Next, subtract 6 from both sides of the equation:

2D = 10

Finally, divide both sides by 2 to solve for D:

D = 10 / 2

Dorji has 5 years of teaching experience.
