OK, first of all, you should have put this is math, but i can help nevertheless.

OpenStudy (ibbutibbu.):

With this, we can make a system of equation..

OpenStudy (ibbutibbu.):

if Pamela's age is 3 times Jiri's age (3x = y), and it says that the sum of their ages is 68, which is (x + y = 68), then our two equations can be made

OpenStudy (ibbutibbu.):

Our two equations are 3x = y and x + y = 68

OpenStudy (ibbutibbu.):

Now, can you solve this, @MikeZack123

OpenStudy (ibbutibbu.):
