Trishia is $9$ $9$ , and Mariel is $11$ $11$

Explanation:

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

$(x + 2) + x = 20$ $(x+2)+x=20$

$x + x = 18$ $x+x=18$

$2 x = 18$ $2x=18$

$x = 9$ $x=9$

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

Hope this helped!
