Answer by ankor@dixie-net.com(22740) (Show Source): You can put this solution on YOUR website!
let t = T's age now
let b = B's age now
;
write an equation for each statement
" tracy is now 3 times older than bob was 2 years ago."
t = 3(b-2)
t = 3b - 6
:
" in four years bob will be the same age as tracy is now."
b + 4 = t
Replace t with 3b - 6
b + 4 = 3b - 6
4 + 6 = 3b - b
10 = 2b
b = 5 yrs B's age
I'll let you find T's age, check the solutions in both statements.
