Best ResponseYou've already chosen the best response.0j = coach johnson's age t = tim's age Coach Johnson is 10 years older than Tim j = t + 10 When Tim started football 3 years ago, Coach Johnson was twice his age t  3 = (j  3)/2 And then you have simultaneous equations. j = t + 10 t  3 = (j  3)/2 Good luck.

Best ResponseYou've already chosen the best response.0Okay, how about use substitution. You know from that first equation what j is; j = t + 10 replace j with (t + 10) in the second equation. so instead of t  3 = (j  3)/2 you have t  3 = ((t + 10)  3)/2 Now solve for t and you can find out what t is.
