Mariel is 2 years older than trisha. the sum of their ages is 20. find their present age?

i cant undersrand this word problem

Answer 1

Trishia is `9`, and Mariel is `11`

Explanation:

Alright, we need two equations for their ages, how about `x+2` for Mariel (since she is 2 years older) and just `x` for Trisha. We also know that together, this equals 20. Now we just need to solve.

`(x+2)+x=20`

`x+x=18`

`2x=18`

`x=9`

So Trishia is `9`, and Mariel is `11`.

Hope this helped!
