**Reiny**, Saturday, November 23, 2013 at 6:54pmRicardo ----- x

Miriam ------ x+4

10 years ago:

Ricardo -- x-10

Miriam --- x+4-10 = x-6

at that time she was 3 times as old as Ricardo

x-6 = 3(x-10

x-6 = 3x - 30

-2x = -24

x = 12

Ricardo IS now 12

and Miriam is now 16

You check the answers to make sure the conditions fit.
