tony and tedy equals thrice their mom age , therefore :y+x=3z , tony is two years younger than teddy :x-y=2 from the first equation : y+x=3z , y+x=3(42), y+x=126 from the second equation : x-y=2 ,x=2+y. subs equ 2 in equ 1 = y+2+y=126 , 2y+2=126 ,2y=124, y=62. subs in equ 2 : x-y=2 ,x-62=2 ,x=64. subs in equ 1 , y+x=3z ,62+64=3z, 126=3z , z =42 . _________________________________________________________ where x=tedy's age , y=tony age , z=moms age :)
